I'm having trouble with my iPhone. This is the 2nd one I've purchased and I'm trying to unlock them both with iphonesimfree.com. The first one unlocked flawlessly, but on the 2nd one, it seems to be unlocked, but I can't get a wi-fi connection - it's greyed out. I'm considering restoring it using iTunes but the warning message in iTunes says it will erase the iPhone and return it to it's factory settings and install the latest software. If I do this restore, will it bring it back to a clean 1.0.2 or 1.1.1? Thanks in advance! As an alternative, should I re-install simfree.app? I've tried erasing the settings on the phone but an icon just spins endlessly....so I'm stuck.
