I got my iPhone after waiting in line this morning. The rep said he activated it and that it didn't need the SIM from my other phone and it would just pop up on the grid in 20ish minutes. I took it home hooked it into itunes, charged it and left it there and went to help a friend move. Got back and it still said no service and my other phone was working fine. So i swapped SIM cards and my iPhone apparently works great and seems to be able to do everything. Was my rep just mistaken - anyone else have to do this? This is a SIM card from a 3G phone, so it looks like there is nothing else special about the SIM that was already in the iPhone - correct?
