Here's my problem:

I'm currently testing a HTC Blue Angel (iMate PDA2k) and a Samsung i730. What I've observed on both devices is that the data connection occasionally drops (GPRS or 1xRTT/EVDO). For the iMate sometimes I can go to the wireless manager and reselect GPRS while other times I have to do a soft reset and then I can reselect GPRS and get it running again. The carrier is T Mobile for the iMate and Verizon for the i730.

For the Samsung I have to launch Internet Explorer so it will dial the modem. I did find that Verizon automatically disconnects the data line at midnight.

My Blackberry never gives me this problem. I know of others (using iMates) with the same symptoms so I am convinced it is related to the operating system and not the carrier. I am expecting the Windows Mobile devices to behave the same as the Blackberry and automatically re-connect to the data line.

Any thoughts or suggestions?
