Unluckily GSM doesn't get as much usable range as old TDMA, so there are
now "holes" they are slowly filling in.
Most TDMA customers are freaked out by how spotty the GSM network is by
comparison. Its only 'real' advantage to voice/sms users is higher
density in very urban areas. You're less likely to wait 30 seconds to
get a call out at a major event or rush hour traffic. Out in the sticks
you're much better off with old TDMA than GSM.
