The GSM Technology is the same. Its that the bands supported by the 8830 (900/2100Mhz) is NOT what the AT&T, T-Mobile, West, Rogers, or Fido networks use in North America ... they all use 850/1900Mhz for GSM/GPRS/EDGE (when it comes to 3G - then that is offered in Blackberry devices this side of the pond - then T-Mobile is the exception to those bands ... using 1700/2100Mhz).
