The DevTeam has released ultrasn0w 1.2 - with a clever feature for those of you who've had an iPhone 3G or 3G[S] 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!
If - AND ONLY IF - you've got either of those devices (3G/3G[S]) and NEED an unlock but can't because your baseband is 05.14 or 05.15... you can now upgrade your baseband to the iPad one (06.15) and use ultrasn0w to unlock. This should NOT be done unless you absolutely need to. Here's the full warning posted by the Dev Team as to why:
WARNING — YOU DO THIS AT YOUR OWN RISK! PLEASE UNDERSTAND THE CONSEQUENCES OF UPDATING TO 06.15.
- 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.[/B]
- 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).
- 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).
This does NOT unlock the iPhone 4 yet. The Dev Team gave this info:
The i4 unlock is taking more effort though, and no further concrete info is available about that yet.
