Z10 Tmobile

Hello,

Tomorrow I am buying Tmobiles Z10. Does anyone know what the model number is going to be? STL100-5? What will be the difference between this phone and AT&T? Best Buy Shows the two phones having different Specs for the radio. Just curious if they are the same.

BlackBerry - Z10 4G LTE Mobile Phone - Black (AT&T) - STL100-3

Under ATT Specs, it show:
Band and Mode 3G|4G|4G LTE|Quad-band
Technology Details LTE|WCDMA/GSM

BlackBerry - Z10 4G Mobile Phone - Black (T-Mobile) - RIM BLACKBERRY Z10 LTE BLACK KIT

and Tmobiles Best Buy Specs show:

Band and Mode 3G|4G|Quad-band
Technology Details 3G|4G

Do they both have the same radio frequency?

Thanks
