An oppertunity has presented itself where I might be able to get a few 850/(1700 or 1900)MHz handsets free from someone in the states who's work is upgrading (downgrading) them all to iphones.
So, would something 850 only work in the cities on telecoms new network or is it 2100 only in cities? Also, is the network smart enough to know the phone has no 2100 so wont try handing calls off the sites that the phone cant talk to?
