Unlocking Without WiFi/Internet
My iPhone 3G's (not 3Gs) wifi has been really sketchy lately (won't see/connect to any networks), so after a network reset didn't work, I decided to try a restore. I restored to 3.1.2, and then jailbroke with blackra1n.
WiFi still doesn't work, so now I'm stuck with an activated iPhone that I can't get internet on since it's not unlocked (I'm on T-Mobile).
Is there a way to install blacksn0w without wifi? (I have internet on the computer, obviously, so I can download whatever I need, but not on the iPhone)
I've read and tired this http://www.hackint0sh.org/f230/95865-2.htm, but I can't connect with iFunBox/DiskAid, since the afc2add isn't on there.
Are there any other options available besides a warranty replacement? (to fix the wifi)
