Update: Download and install blacksn0w unlock for iPhone 3G or iPhone 3GS
When Apple released the iPhone 3.1 firmware, it updated the baseband (modem firmware) for all iPhone 3G and 3GS users and fixed an exploit that allowed iPhone users to software unlock their iPhones. While there were some iPhone users that were smart enough to wait and update using iPhone Dev Team’s PwnageTool software, many people still updated through iTunes unknowingly and their unlock was compromised. While the firmware on an iPhone can be downgraded, baseband upgrades are permanent. For months iPhone owners that had their baseband (or modem firmware) updated to version 05.11.07 were left without an unlock.

Fortunately on November 4, this is all going to change. Expert iPhone hacker, Geohot has found an exploit in baseband 05.11.07  which will allow iPhone 3G or iPhone 3GS users to get their iPhone unlock back! At this moment Geohot  is working on his iPhone unlock dubbed blacksn0w and he plans to release it to us on November 4. As of this posting, Geohot has released nothing more than a screenshot with some random code, and a music video on YouTube (which you can see below), but we still trust him.

WARNING

Now that I’ve told you the good news, it’s time to tell you the bad news. The exploit that Geohot found (AT + XEMN) has been posted on the web, and I’m pretty sure it will be patched in the next update. I don’t know all the technical details of how this unlock works, but I do know that Apple is getting closer and closer to patching all the holes that are present in their baseband. Apple will most likely update their baseband in the next iPhone firmware update and patch the exploit that blacksn0w uses. Once Apple does that, iPhone users that update must not update using iTunes and instead they should wait for iPhone Dev Team to release their PwnageTool software that allows you to update without upgrading your baseband.
