UltraSn0w Now Unlocks iPhone 3G, 3GS on Newer BaseBands (Update)

Advertisement

Yes, today is the day when most of us in need of a carrier unlock for at least the older models of the iPhone get to celebrate. There’s a lot of technical information provided by the Dev-Team on this update, but bottom line is it allows you to unlock your iPhone 3G and 3GS to work on any GSM carrier by using the new version of UltraSnow.

Update: Given some problems some of our commenters have been having, it evidently seems that this new unlock requires you to load an iPad baseband on your iPhone 3G or 3GS. Sadly this is not for beginners, but if you’re up to it, here goes:

Quoting the Dev-Team: Today we’re pleased to announce our free carrier unlock for iPhone3G/3GS owners with a baseband later than 05.13.04.

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.

SIMPLIFIED VERSION:

– Read and fully understand the warning on this post.

– Download this IPSW

– Run PwnageTool to create a custom 4.1 IPSW. Tell it you want to use the iPad baseband you just downloaded. Restore to this custom IPSW.

– Install ultrasn0w through Cydia

– Enjoy!

If you don’t have a Mac, redsn0w will be released within a few hours to handle this.

So yeah, this isn’t much of a beginners solution, but they say it works. Given the level of difficulty on this update, our advice is that if you terribly need to upgrade, do so at your own risk. If not, the updates offered are not compelling enough for you to risk loosing your current unlock, unless you’ve done your homework to be able to downgrade.

Update 2: Redmond Pie has just prepared a great video tutorial to give you a hand on this process. Their tutorial can also be accessed here.
