Most of iPhone 3G and iPhone 3GS users updated their baseband to iPad's one which is 06.15.00 to be able to unlock it. It's not possible to restore using stock firmware on iPad's baseband so you can downgrade to baseband 05.13.xx which is unlockable using ultrasn0w and you'll be able also to restore using stock firmware on this baseband.


This method is not official from the iPhone Dev Team. They are still working on an easy-method to downgrade 06.15.00 baseband to lower ones on both iPhone 3G / 3GS. This method works only on iPhone 3G bootloader 5.8. Follow the steps as mentioned on RedmondPie below:

Here’s what you will need:
- Jailbroken iPhone 3G
- Fuzzyband installed via Cydiaafc2add installed via Cydia
- i-FunBox (for Windows) or DiskAid (for Mac)
- Certificate to use with Fuzzyband.

And the step by step procedure is as follows:

STEP 1: Download the required certificate file ICE2-06.15.00.cert from here.

STEP 2: Install Fuzzyband from Cydia and start this app.

STEP 3: Connect your iPhone 3G with computer via USB cable.

STEP 4: Start i-FunBox and click File, then navigate to Applications/Fuzzyband.app, right-click and then select Copy from PC.

STEP 5: Select the ICE2-06.15.00.cert file you downloaded earlier and then copy it to this location:Applications/Fuzzyband.app.

STEP 6: Now simply disconnect your iPhone from your computer and start Fuzzyband app (which you previously installed using Cydia) on your iPhone.

STEP 7: In Fuzzyband, you will now see your current version of Baseband, (which should still be 06.15.00). But now you will have the option to downgrade it to version 05.13.xx.

Once you have downgraded, Go to Settings –> About, and scroll down to check your Baseband which should now read 05.13.xx (which is unlockable via Ultrasn0w). You can now also update or restore any firmware without iTunes throwing errors. 

So, got it? Fell free to leave us a comment with results !

After MuscleNerd has declared about the new amazing Redsn0w jailbreak features, he has been asked about the downgrade for 6.15.00 baseband on iPhone 3GS and 3G after using ultrasn0w, he points that the work on the downgrade issue won't start only after the release of iPhone 4 baseband 2.10.04 unlock which expected to see the light in less than a month.

Fammbizz asking MuscleNerd: when is ur bb downgrade comin out for 6.15.00
MuscleNerd replying: TBH (to be honest), that won't be looked into until after i4 unlock

Many of users who unlock their devices using ultrasn0w 1.2 noted problems with their GPS, so we expect that downgrade will fix this bug, moreover, there is speculation about the possibility to downgrade the baseband to unlockable one which will be compatible with the old version of ultrasn0w. Stay tuned

In case you have unlocked your iPhone 3GS / 3G by flashing iPad baseband 6.15.00 with ultrasn0w 1.2 on iOS 4.2.1, and have issues while restoring your device, here is Sherif Hashim the guy behind ultrasn0w unlock tool, has posted a simple guide showing how to restore your iPhone 3GS / 3G to avoid iTunes errors.


Note: To restore your iPhone 3GS from 4.2.1 to 4.1, you must have saved SHSH blobs for iOS 4.1.

For PwnageTool users:

A :  If you are on Mac and use PwnageTool: If you used pwnage tool then you will have to create a “new” custom 4.1 or 4.2.1 and say “No” when you are offered the BB update to 6.15.00 since you already have it, then build the custom ipsw and restore to that.

For Redsn0w users:

B : If you use(d) Redsn0w:

B.1: If you are currently on 4.1, then you can restore to official 4.1 again, and when you see error 1015 pop-up, you kick your device out of recovery mode using TinyUmbrella, use redsn0w and don’t check “ipad BB update” because you already have that Here Is How To Restore iPhone 3G And iPhone 3GS While On Baseband 06.15.00 And Having Issues icon smile

B.2: If you are currently on 4.2.1 then you’ll have to restore back to 4.1 (because 4.2.1 will not allow you to kick the phone out of recovery when 1015 occurs due to the silly BB / iOS mismatch check added there) , then do the same steps as CASE-1.

How to go again to iOS 4.2.1:

If you want to go again to 4.2.1 your only way is to use a custom 4.2.1 done by pwnage tool in the same steps mentioned in A .

Try Hashim's methods above to restore you device between 4.2.1 and 4.1, it worth trying. Don't forget to tell us about your experience.

Few minutes ago p0sixninja the hacker behind Greenpois0n jailbreak has just announced that the new version of Greenpois0n is being updated to be untethered jailbreak for iOS 4.2.1 on iPhone 4,3GS iPod touch 4G, 3G and iPad, but the untethered task has caused a delay in releasing the new Greenpois0n.

I apologize for the delay in greenpois0n 4.2.1 support. Our current focus is on a permanent untether solution

Till now there is no ETA (estimate to arrival) for the new Greenpois0n. By the way Comex is also developing a new method to make untethered jailbreak for iOS 4.2.1 on all devices and it's expected to see the light on Christmas.

Few minutes ago, a new mix-up between iPhone dev-team and sbingner, has been done to allow you to activate your iPhone 4, 3GS and 3G without using original SIM or Hactivation. Thanks to sbingner's new tool which called SAM (Subscriber Artificial Module) and redsn0w 0.9.6b6. Moreover this mix-up has fixed the battery consuming after unlocking iPhone 3GS/3G with ultrasn0w 1.2. Let's check out how use this package after the jump.


STEP 1: Download Redsn0w 0.9.6b6 for Windows and Mac, (Links at the end)

STEP 2: For iPhone 3GS/3G users follow our previous guide posted here, for other devices follow this guide, (But be sure you are using Redsn0w 0.9.6b6)

STEP 3: After you finish jailbreaking your device, start Cydia and add http://repo.bingner.com repository.
STEP 4: Then install “SAM” and “SAMPrefs”.

STEP 5: Launch Redsn0w 0.9.6b6 again, and select “Deactivate” option.
STEP 6: Navigate to Settings > SAM and click "De-Activate iPhone"

STEP 7: Connect your iPhone to your PC then launch iTunes, allow iTunes to activate your iPhone officially. You will see this message "iPhone is activated"

According to sbingner : If iTunes says invalid SIM, you will need to manually select the appropriate carrier under one of the methods besides "Automatic" and click on a SIMID.

STEP 8: Here's the final step, go now and follow our guide posted here to unlock your device with ultrasn0w 1.2

Download Redsn0w 0.9.6b6 for Windows and Mac.

iPhone Dev-Team has just released redsn0w 0.9.6b6 (Windows and Mac) to jailbreak iOS 4.2.1 on iPhone 3GS/3G and update their basebands to iPad baseband 6.15.00, as most of you know that redsn0w 0.9.6b5 did that, but the new version of redsn0w 0.9.6b6 brings activation without
hacktivating, or using original SIM card and increases battery life substantially, as we reported earlier, it was the most prevalent problem after unlocking iPhone 3GS/3G with ultrasn0w 1.2

Developer @sbingner (author of TetherMe) has made some excellent progress devising a new hactivation method that kills two birds with one stone for all you ultrasn0w unlockers.  His tool, “Subscriber Artificial Module (SAM)” tricks your iPhone and iTunes into creating legitimate activation tickets even though you’re unlocked with ultrasn0w.  This means you get the full benefit of push applications, and your battery life increases substantially.  If you’d like to try it out, check out http://www.bingner.com/SAM.html

To help make it easier to try out @sbingner’s tool, we’ve updated redsn0w to include a new “Deactivate” option for the 3G and 3GS.  Use this option *after* you’ve installed SAM…it will remove the normal patches made to lockdownd and let SAM take over.  (sbingner plans on making a button to do this within SAMPrefs too).  Great work, @sbingner!

Thanks @sbingner for the hard work, as usual we will prepare the full step by step guide, showing you how to use SAM and the newly redsn0w 0.9.6b6. Stay tuned.

UPDATE: Here is the step by step guide showing how to Activate iPhone 4, 3GS, 3G Without Original SIM or Hacktivation with SAM & Redsn0w 0.9.6b6 Click Here.

The newly released ultrasn0w 1.2 which unlocked the iPhone 3GS/3G running iOS 4.2.1 by flashing the iPad baseband 06.15.00 using Redsn0w 0.9.6b5 or PwnageTool 4.1.3, has caused two major issues for many iPhone 3GS/3G users, ultrasn0w 1.2 has led to aggressive battery drainage, in addition,
iPhone becoming excessively hot. Sherif Hashim, one of the hackers behind ultrasn0w has addressed these issues, let's check out them after the jump.

Here's Hashim justifying these issues

i hope those of u with 3g/3gs are enjoying their updated unlocked devices, all props to @MuscleNerd & co. for making this possible :) , hopefully the iphone 4 on 2.10.04 and 3.10.01 follows within a good time table.

on a very important side note, before anyone starts to complain about battery drainage issues after installing the new ultrasn0w on the 6.15.00 updated BB, the culprit here is not ultrasn0w, it's the hacktivation process (activating the phone by pwnage tool or redsn0w rather than using an official carrier sim to do so) that u mostly did while jailbreaking.

The 4.1 and 4.2.1 ipsws unlike their old ancestors, seem to keep looking for valid push certificates all the time, either thru your wifi, or thru your cellular data network (which u only have after installing ultrasn0w and hence u accuse it) , this can be seen clearly if u have a cellular working data plan for 3g or edge and u watched the settings > general > usage > cellular network data (sent & received are continuously increasing even without using any internet traffics on the phone) , this will also render the phone going hot even in stand by mode and also very rapid battery drainage occurs plus consuming ur data if you were not on an unlimited plan.

How can you fix these problems:

so to resolve this, u either:
A) 1st Solution: try to activate the phone using the official sim if u have it (even if the sim itself is old and not working) , or borrow it from a friend if it's possible, by any means, try to have an access to one and use it

B) 2nd Solution: if A is not feasible, u can install SBsettings from featured cydia packages and turn wifi and data off when u r not using it (shuts down both 3g and edge) , till C is done

C) 3rd Solution: there is a very nice module being worked on by a trusted jailbreak app dev, namely @sbingner , which ll resolve that issue for those having it, the details of which shouldn't be disclosed until he finishes his awesome work, till then, either use A or B to resolve the issue if it exists for you

In case you're one of those who suffering from the above mentioned problems after unlocking their devices with ultrasn0w 1.2, you have to try the above solutions as they will handle the situation, but don't forget to feed us back with your results on the comments section.

Just a couple of hours back, the iPhone Dev Team has updated their carrier unlock tool which brings unlock for iPhone 3GS & 3G on iOS 4.1 or iOS 4.2.1 but unfortunately, you have to update your device's baseband to 06.15.00 to be able to unlock it.

The iPhone Dev Team has just released ultrasn0w 1.2 which brings carrier unlock for iPhone 3GS and iPhone 3G on iOS 4.2.1 or iOS 4.1.

From the iPhone Dev Team Blog:

Today we’re pleased to announce our free carrier unlock for iPhone3G/3GS owners with a baseband later than 05.13.04.  The unlock for that baseband exploited the AT+XAPP command, thanks to a crash initially discovered by @sherif_hashim (@Oranav also found this crash).  So what hole are we exploiting today, since Apple closed that AT+XAPP hole?  Well, we’re exploiting the exact same hole!

It turns out that the very first iPad firmware 3.2.2 has baseband version 06.15.00 still vulnerable to AT+XAPP.  The iPad baseband is built for the exact same baseband chip as the iPhone3G/3GS — they’re fully compatible!  Some of us have been running 06.15 for weeks now on our iPhones in preparation for this release.

Since 06.15 is a higher version than 05.14 or 05.15 (where AT+XAPP is gone), anyone stuck at those versions can simply upgrade to 06.15 to unlock again!  Luckily for us, Apple *still* provides the iPad FW 3.2.2 with this vulnerable baseband right from their own servers. (Grab it now, before they take it down!)
We’ve been busy updating both PwnageTool and redsn0w to make the baseband update as seamless as possible.

1. First up is “PwnageTool 4.1.3 Unlock Edition”.  It has a special dialog box which will ask you if you want to update to the iPad baseband.  You must already have the iPad 3.2.2 IPSW on your computer (see the above link)….so just point PwnageTool at it (or let it find it on its own if you’re in “simple” mode).
2. Directly after PwnageTool 4.1.3 is available, the official ultrasn0w repo http://repo666.ultrasn0w.com will be updated with ultrasn0w 1.2, which covers iPhone 4 baseband 01.59.00 and iPhone 3G/3GS basebands 04.26.08, 05.11.07, 05.12.01, 05.13.04 and now 06.15.00.
3. Finally, we’ll release an update to redsn0w today for those without Macs and can’t run PwnageTool.  The new redsn0w will give you the option to update your baseband to 06.15 too.

WARNING — YOU DO THIS AT YOUR OWN RISK!  PLEASE UNDERSTAND THE CONSEQUENCES OF UPDATING TO 06.15.

1. There is no way to come back down from 06.15, and there’s no hiding the baseband version from Apple.  You’ll be voiding your warranty in a very obvious way.
2. If some future baseband comes out with a critical fix, you won’t be able to update to it if it remains down in the 05.xx sequence (then again, you wouldn’t update to it if you wanted to keep your unlock anyway).
3. Starting with FW 4.2.1 if you have 06.15 on your iPhone you won’t ever be able to restore to stock firmware (it will fail).  You’ll need to only restore to custom IPSWs (then again, if you’re unlocker you should already be doing that).

Certainly don’t update to 06.15 if you don’t need to!  Only do this if you need the unlock and you’re stuck on 05.14 or 05.15, and you’re willing to assume the above risks.

This PwnageTool also contains a 4.2.1 bundle for iPhone3G owners…for all else, it’s still only 4.1.  If you have an iPhone3GS with an old bootrom, the new redsn0w will handle 4.2.1 for you (in fact it covers 4.2.1 for all devices, even though some of them are still tethered at 4.2.1 until @comex can work some untethering magic).  iPhone3GS users with old bootroms who want to go to 4.2.1 should not use this PwnageTool!  Update to stock 4.2.1 first, then use the upcoming redsn0w to update your baseband.

• Now select repo666.ultrasn0w.com from the sources list and at last select ultrasn0w from the list of packages as shown below then install this application.

STEP 3: Almost done, now simply reboot your iPhone and you should have a fully unlocked iPhone 3GS on iOS 4.1 or iOS 4.2.1.

Unfortunately, iPhone 4 unlockers have to wait a bit longer before they can use their device on any carrier they like but at least they had promised to start working on that starting from tomorrow.

MuscleNerd of the iPhone Dev Team has just tweeted that Ultrasn0w unlock is on it’s way and you’ll be free at last. The unlock for iPhone 3G and iPhone 3GS on baseband 05.14.02 (iOS 4.1) and baseband 05.15.04 (iOS 4.2.1) will be released this Sunday.

Good progress today…everything is on track for updated ultrasn0w by Sunday/Funday at the latest (longer for iPhone4!)

MuscleNerd has wished a happy Thanksgiving today for everyone and told people not to wait for unlock today because they celebrate with their families too! Apparently, the latest Ultrasn0w update will work with iPhone 3G and 3GS and it may take a bit longer to release iPhone 4 integration. Anyway, stay tuned as we'l post immediately whenever the tool is updated and available.

Few moment ago we broke the news about the release of Redsn0w 0.9.6b4 to jailbreak iOS 4.2.1 on iPhone 4, 3GS, 3G, iPod touch 4G, 3G and iPad with working MobileSubstrate, as we told you earlier that redsn0w 0.9.6b4  is based on GeoHot’s limera1n bootrom exploit.


The bad new is that right now, the redsn0w 0.9.6b4 is a tethered or semi-tethered jailbreak for some devices (i.e. you will lose your jailbreak every time you reboot your iDevice, so you have to follow the following steps every reboot to have a jailbroken device )

Untethered Devices:

• iPhone 3GS (old bootrom)
• iPhone 3
• iPod touch 2G (Non-MC Model)

Tethered Devices:

• iPhone 3GS (new bootrom)
• iPhone 4
• iPad
• iPod touch 2G (MC Model)
• iPod touch 3G
• iPod touch 4G

NOTE: Those of you who rely on a carrier unlock stay away from Redsn0w and iOS 4.2.1.

GUIDE:

STEP 1: Download redsn0w 0.9.6b4,  iOS 4.2.1 for your device(download links at the end).

STEP 2: Update to 4.2.1 firmware using the IPSW file you just downloaded via iTunes 10.1.

STEP 3: Launch Redsn0w 0.9.6b4,  and browse for iOS 4.2.1 firmware final version 

STEP 4: Select "Install Cydia" and click on "Next"

STEP 7: You will Get a Jailbroken Device on the latest iOS 4.2.1  as soon as the process ends.

STEP 8: This step is only for these devices iPhone 4, 3GS (New Bootrom), iPod touch 4G,  3G, 2G, iPad. While this is tethered jailbreak and whenever you want to do anything related to jailbreak like SSH your device, or running Cydia, you must first run your device in the so called “jailbroken state” on every reboot by using “Just boot tethered right now” option.

Download iOS 4.2.1 (Final version) for your device version.
Download Redsn0w 0.9.6b4 for Windows and Mac
Download iTunes 10.1 for Windows or Mac

As most of you know, AirPrint may be the most interesting feature in the newly released iOS 4.2.1 that allows you to print documents and files directly from your iPhone, iPad or iPod touch. But not all devices will be able to enjoy this function, so we will show you how to enable AirPrint on non-supported devices as iPhone 3G and iPod touch 2G.


STEP 1: Download Redsn0w 0.9.6b3 (Windows - Mac OS X).

STEP 2: Download iOS 4.2.1 original firmware from here.

STEP 3: Connect your device into your computer via USB and launch Redsn0w you download in step 1. Click on browse and point it to the original iOS 4.2.1 firmware of your device and wait while it's recognized.
STEP 4: Now you have to check on Enable Multitasking, other items are optional.
STEP 5: Put your iPhone into DFU mode by following the instructions on the screen:

• Hold down the Power button for 5 seconds.
• Without releasing the Power button, also hold Home buttons together for 10 seconds.
• Now release the Power button but keep holding the Home button for 15 seconds.

STEP 6: Once done, your iPhone will be rebooted and you'll get AirPrint on iPhone 3G ad iPod touch 2G.

From now on, when you open a page in Safari, you'll see the Print button by clicking on the share icon at the bottom. With this option, you can set how many copies of documents you want to copy. You have to select the printer (must be one of the 11 supported printers) and hit Print.
In case your printer is not supported by Apple, you can download and install Printopia to enable AirPrint on non-supported printers. [iPhoneItalia]
