I cam across a good question on the MSDN support forums. If you've every tried to debug a program that uses a Data Connection hile the device is connected to your computer you may have found that the device won't use it's own data connection and will instead pass all of it's data request through the ActiveSync connection. This can be frustrating when the verything you are trying to test is the devices data connection. There's a simple solution. In the Windows Mobile Device Center (or ActiveSync) uncheck the box labeled "Allow data connections on device when connected to PC."
