Hey guys, I recently got an iPhone from a friend at school at a very reasonable price I dont know a thing about these unfortunatly, but I planned on simply using it as an iPod, because i have a phone already, and this one doesnt actually have a sim card.... My issue is, I have downloaded and connected it up to iTunes, and it has downloaded an update, but now says that I must have a sim card inserted to continue. On the iPhone screen it says "No SIM card installed. Insert a valid SIM with no PIN lock to activate iPhone." :S is there any way to simply use it as an iPod without needing a sim card?? help appreciated!!
