I have searched the internet all day and I can't find any information on this, can someone tell me if I can activate an iPhone 4S without a sim card? The phone is either Sprint or Verizon. Its definitely not AT&T because I tried my AT&T sim and it tells me only supported sim work. Please I want to use this phone as an iPod touch at the very least! Thanks I don't have an account with Sprint or Verizon.
