NonprayingMantis:Wade: You could do with XT but available handsets are less exciting and not always useable on the other networks should you decide to jump ship
actually it's almost the exact opposite.
XT handsets are always useable on Voda or 2Degrees (sometimes not with nationwide 3G, but definitely at least GSM) whereas Voda and 2D handsets probably won't work on XT (except the iphone)
In respect to this conversation we are discussing iphones/smartphones so the ability to process 3g data would be a pre-requisite so therefore my point stands
