so my friend gave me his old iphone to use as an ipod, it's a 2g, and it was working fine as an ipod, and i wanted to put more music on it so i plugged it in, and itunes said i had to restore it, so i did, and then when it was done restoring it said to put my sim card in and activate it, but i can't afford to have the iphone plan so i just wanna use it as ipod. but now it won't let me use it until i activate it. anyone know how to get around activating it? please help, i need my music ):
