freitasm:jaidevp: We have 2100 in the following locations, there are more will advise after looking up :)
In another words: don't bother with 2100 Mhz devices. you won't have coverage everywhere. A 850 MHz device will give you 100% coverage on XT.
ok. i have been looking at buying a smart phone but cant realy find one the has 850hmz frequency
