Ok title seems roff so let me explain it.
If you don't want to wait for the launch and wanna buy from someone from the US or like EBAY don't be fooled
If you want at 3g version MAKE SURE that they are AT&T and not Verizon.
Verizon use a different technology that is not supported by our carriers, so if you buy a Verizon 3g you cannot use BELL Rogers or TELUS cards,
So make sure to buy an AT&T :P
