Hi, Will the HTC Desire use 3G data with T-Mobile USA? The HTC desire 3G frequencies are: HSPA/WCDMA: 900/2100 MHz T-Mobile USA uses: AWS 1700/2100 MHz Will it work? I.E. do both frequencies have to match, or just one? or is AWS different from HSPA/WCDMA? It the normal GSM/data is quad band on the phone so should be no problems there (phone has 1900mhz and T-Mobile USA uses 1900mhz) Many thanks in advance.
