yeah be careful
apparently over in yank land, the phones are comletely integrated or something, so you have no SIMM chip on a lot of you phones.
if your phone had a SIMM card theres a possibility you either had a offline phone (works with any SIMM chip) or you can get it hacked by someone with a cable and the software
BUT
each phone has a unique code. over here the phone networks are sooo damn lazy they have the ability to lock out a phone dialing up their network with that code, ut they dont
if they dont there u might get away with it
i wouldnt bother personally
