I use the pda to test software and design small interfaces. I had the cheap software and little gps unit that is pretty small. One cell phone is off contract, it's the verizon. The cingular is my home phone transferred to cellphone. I wanted to keep my home phone number I've had for 20 years but Verizon COULD NOT transfer it. I tried. I call my verizon friends on the verizon and cingular on that phone. Also Cingular gives you a rollover plan. I have too much stuff to carry and like to keep things compact and cheap. I have high-speed internet at home with an N router. I would like to share this with a neighbor who lives nearby and split the cost. All this data and phone stuff I want to pare down as much as possible without losing quality. Help!
