I bought a copy of PDA net for the 700p. I have had nothing but disconnects, or lock ups while using it. Now, it won't talk to the desktop. I am using a usb cable not BT. Hotsyncs work fine with the cable. I have tried it with the EV-DO checked, and unchecked. Dialup setting, and proxy, neither work. I have re-installed the .prc file, and the desktop software. Help!
