Hey I'm just after some quick clarification regarding service bands.


I'm looking at a phone which is HSDPA 850 / 1900


This in theory should work on XT right? 


I'm just wondering what the difference between the 850 / 1900 vs 850 / 2100.


As in is one better than the other, or does it not really make any difference.


Thanks, sorry if this has been covered before
