UPDATE #2: AT&T iPhone can be factory unlocked on any iOS or baseband. Unlock it now.
UPDATE #1: Use Turbo SIM to unlock your iPhone 4 now.
It sure is busy with the iPhone Dev Team as we just found out that besides them working on a fix for the GPS issue, 6.15.00 baseband downgrader, new Greenpois0n for untethered iOS 4.2.1 jailbreak and the unlock for iPhone 4 with basebands 2.10.04 or 3.10.01; apparently they may also be working on a baseband downgrader for iPhone 4!
It has not been revealed how the tool would work but most likely it would be something like Fuzzyband; which was developed to downgrade iPhone 3G baseband with old bootloader. iPhone 4 has basebands 2.10.04 and 3.10.01 – both cannot be unlocked yet. The only iPhone 4 baseband which has been unlocked is version 1.59.00.
Speculatively speaking, this is probably just a concept for now as mentioned by @MuscleNerd on this Tweet reply to a user:
@mfaizulislam: for Baseband downgrade, can it be applied to iPh4 ?
@MuscleNerd: conceptually, yep probably. But new i4 unlock must precede that because otherwise, nothing to downgrade from 01.59 to

The developer behind TinyUmbrella has just announced on his website that you will soon be able to restore your iPhone, iPad or iPod Touch without using iTunes. This will be a great leap forward from the current restoring methods and definitely will be useful for jailbreakers or unlockers.
UPDATE: Restore your iDevice without Using iTunes and Losing Your Jailbreak
Here’s what was posted on his website:
“I’ve been working on a new and improved version of TinyUmbrella that will, among other things, allow you to restore your iDevice without iTunes. With the holiday season and work, this will take me a bit to get working the way I want it. I appreciate your patience and your support. You guys are awesome :) No ETAs yet but I’ll post updates here and on twitter.”
Through the use of TinyUmbrella, we believe that many types of iTunes errors you see during the restore process may be eliminated completely. That would definitely save you from hours of headaches and possibly making any jailbreaking work more streamlined and simplified – something that everyone would love.
We hope to hear other good news before the end of the year – Fix for the GPS issue, 6.15.00 baseband downgrader, new Greenpois0n for untethered iOS 4.2.1 jailbreak and most importantly the unlock for iPhone 4 with basebands 2.10.04 or 3.10.01.
Let’s be thankful for these folks who are constantly working hard and opening up many possibilities for everyone in the iPhone world.
When the iOS 4.2.1 was finally released on November 23, the iPad skipped iOS 4.2 for 4.2.1, it was assumed that the Wi-Fi problems were resolved.
However, that may not be the case, with a number of users reporting degraded Wi-Fi performance since upgrading to the latest iOS. There’s also a thread on Apple’s support discussion forum where people are expressing their frustrations about the upgrade.
Someone also claimed that Apple is removing posts from the forum that refer to downgrading to iOS 3.2.2 – which is apparently the only fix for those having issues – or suggest emailing Steve Jobs directly. While the latter is probably pointless and reasonable for Apple to remove, it is disappointing to see a possible fix being taken down because Apple doesn’t officially support downgrading the iPad’s operating system.
The support thread has generated over 55,000 views and more than 500 replies, suggesting the issue is widespread.
We had the opportunity to go through the threads and some users have found some workaround or at least temporary fixes. Since the problem lies with the iPad so you can only work on your Wi-Fi router.
You can try one or all of the following on your Wi-Fi router:
- Set security to use WPA2-AES or
- Set security to use WEP-Auto
- Change the network mode to 802.11g/n mixed mode
- Change the frequency to channel 1

If you are one of the many iPhone users who have upgraded to iPad’s baseband 6.15.00 using redsn0w and having battery drain, GPS and other issues – here’s a good news – the ability to downgrade your baseband from 6.15.00 to an earlier baseband version may be available soon. This was confirmed by @MuscleNerd on replying a tweet question by a user.
@Lezanz: what about GPS issue? Any progress?
@MuscleNerd: sorry still collecting data on that. But also working on a bb downgrade (!) method for those with unlockable bb
Again, no ETA – let’s be thankful that they are dedicating a lot of time to come up with a fix for us!
@MuscleNerd from the iPhone Dev Team has just confirmed on his Tweeter that they now have untethered jailbreak working on the latest iOS 4.2.1 firmware.
For newbies out there, tethered jailbreak means each time your device loses battery power or needs to be rebooted, you must attach it to a PC or Mac to boot into the jailbroken state. So untethered jailbreak is the opposite, and of course is the most prefered type of jailbreak.
He elaborated that this a “backup” plan to @Comex’s (who did the Jailbreakme Star 2.0) upcoming userland method and that it is generalizable.
“Got “backup plan” for untethered 4.2.1 JB working (video coming up). Uses mysterious 4.2b3 hashes Cydia kept for you.
(It’s a “backup plan” because comex is working on a more extensible one, but this method is also generalizable)
ipt4g 4.2.1 untethered JB w/4.2b3 kernel: http://is.gd/inE4e … Wastes no exploits, but upcoming @comex JB maybe better”
These dedicated and hardworking folks are going to make things happen again! As usual, there will be no ETA, but as always, it is worth the wait.
