UltraSn0w Unlock for iPhone 4.3.1 Will Be Released Tonight

After recently releasing their jailbreak for iOS 4.3.1 via PwnageTool and RedSn0w, the Dev Team is now getting ready to unleash their UltraSn0w unlock.

UltraSn0w Update is Almost Ready for iOS 4.3.1, Fixes Bug Issues and Older Baseband Compatibility

MuscleNerd has confirmed that UltraSn0w update is coming for iOS 4.3.1 in a few days. The unlock tool has had several bugs and is currently incompatible with several older basebands.

To clarify: the upcoming UltraSn0w update will not unlock any new basebands. The update is meant for current unlockers that wish to update to the latest 4.3.1 jailbreak and keep their unlock.

More Details About iPhone 4.3.1 Unlock Emerge

Just to preface this before anyone gets the wrong idea; there is still no new baseband unlock available.

Now that the formalities are out of the way, I think it’s safe to tell you that new details have been revealed about the existing baseband unlock and its compatibility with the soon to be released untethered jailbreak for iOS 4.3.1.

Depending on when the jailbreak is actually released, if you rely on an unlock, you may have to wait a while until a new version of UltraSn0w is released. This is due to some compatibility issues between iOS 4.3.1 and the current version of UltraSn0w.

Fortunately, you won’t have to wait long, as the latest tweets from members of the iPhone Dev Team confirm…

Is an iPhone 4 Unlock For Basebands 3.10.01 and 2.10.04 Right on the Horizon?

If you’ve been using an iPhone 4 on basebands 3.10.01 or 2.10.04, your inability to unlock has undoubtedly been an issue of great concern.

Time and time again, we get our hopes up, only to come away disappointed.

Let’s give Apple credit, they’ve done a decent job with keeping these basebands locked down for a significant amount of time, but the gates could be breached in the very near future…

iPhone 3G on BaseBand 06.15.00 Unlocked for Life

It’s official. If you have an iPhone 3G on baseband 06.15.00 and you are unlocked , you better get comfortable. MuscleNerd confirmed in a recent tweet that since the iPhone 3G will not be receiving the 4.3 firmware upgrade, your iPhone 3G will remain unlocked indefinitely.

Now let’s not all panic, this only affects iPhone 3G users on the above mentioned baseband. If you are unsure of your baseband version, you can go to settings -> general -> about -> modem firmware.  For most of us this isn’t a huge deal, but to iPhone 3G users who unlocked using the 06.15 UltraSnow unlock, and have been experiencing GPS issues, this is devastating…

Download Redsn0w Beta for iOS 4.2 Untethered Jailbreak

The Dev Team has released their Redsn0w beta, dubbed Redsn0w 0.9.7b1 for iOS 4.2. We wanted to alert our readers, and at the same time provide a word of caution about the beta release.

To quote the Dev Team “This is a beta tester program. It’s not a general release!  Things can go very wrong, so please don’t even consider testing if you have pictures or other media on your device that you haven’t backed up!”

For that reason we recommend you hold off until the official release, especially if you rely on an ultrasn0w carrier unlock…

Today, some good news was uncovered about an unlock for the iPhone 4 iOS 4.2.1 baseband 02.10.04 in a tweet sent out by Sherif Hashim. The iPhone hacker confirmed that an unlock for 02.10.04 will be available, most likely before January 16th…

Fix: iPhone Battery Drain After Jailbreaking and Unlocking

As we reported earlier this week, some of you who have recently updated your baseband to 06.15.00 to jailbreak and unlock have been facing battery drains issues. The problem doesn’t actually come from UltraSn0w or RedSn0w, but from the hacktivation process, for those of you who have hacktivated instead of activating the phone with an official carrier.

The issue comes from iOS 4.1 and 4.2.1 which constantly look for valid push certificates, either via wifi or your data plan (Edge or 3G). This runs down you battery and may even cause your iPhone to overheat. If you didn’t hacktivate your iPhone but simply activated it with an official carrier (ie AT&T in the US), you shouldn’t have any problem.

If on the other end you did hacktivate your iPhone, you might be experiencing the battery drain issue. Fortunately, there is now a fix for it…
