Allright i have been using a Pocket PC for a more than couple of years, A HP IPAQ WOULD BE A GOOD ONE IT IS GSM/WIFI/BLUETOOH its pretty cool but the procesor is little slow so you might for now want to go with Cingular 8125 or Tmobile MDA (which is HTC Wizard) which has has the same processor little faster and biggger memory, I like the pocket PC by Palm treo but its verizon and does not have an WIFI, If you really have the money you might want ot get a HTC tytan, you can find one on ebay for like 700 bucks its has all the feature of cingular 8125 but has a better processor. the Processor in the HTC wizard is just 200 MHZ but its a dualcore processor one core is responsible for phone operatoins and the other one is for the OS this should help u
