The Dev Team has just announced that they have been successful in attaining carrier unlock for the iPhone 3G and iPhone 3GS, which is now available through Cydia.
Same old, same old, I know. But what’s more interesting is how the Dev Team managed to unlock these old devices: by patching in a vulnerable baseband from the first iPad firmware!
The Dev Team explains:
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.
Ouch! Here’s hoping no Cupertino heads roll over this one.
