Ok, so my friend asks me to do a few things for his iphone 2g. I download itunes, and connect the iphone 2g. It said there was a software update; Unfortunately, i thought there was no harm, so i clicked yes- to update to the new software. It downloaded the new ware, and i restored the phone. NOW the problem is that i realized my friend's iphone was UNLOCKED. When i connect the iphone, it says "The SIM card inserted in this iPhone does not appear to be supported." I realize now i made a mistake by updating the ware. Is there anyway to get it back to the way it was? My friend is going to kill me.
