Just curious as to see if any of you out there have used your PDA as a phone/GPRS system. I have T-Mobile and I am really considering trying to convert my PDA to a mobile smart phone. I really like the WM5 interface and was hoping somebody can school me on this on how to go about doing it. I have seen some Compact Flash Card GSM/Sim readers, but i'm not sure if they provide vibrate mode.

Help!
