Since I travel a lot I've decided to buy my self an Ipad 2 wifi+3G in States. But whereever I look there's only AT&T or Verizon versions. Now I know that Verzion is useless for me since it uses CDMA chip but how about AT&T? I would like to put in other GSM/UMTS etc SIM cards and be able to use my own data plan. I've searched google which says Ipad 2 devices are unlocked to mobile operater but I've just had a chat with an assistant from one of the largest gadget stores in USA which told me I won't be able to use it with my SIM card. So you guys can help me out? I would like to be sure and not to buy locked device which is for me worthless.
