The security mechanisms in place in Windows Mobile make it very difficult to persist login credentials through a cold-boot.

Following is a description of the scenario where may demonstrate this problem:

If a Dolphin has login credentials saved for a GPRS connectoid, and the RegBackup utility has been executed after saving these credentials, and the Dolphin is subsequently cold-booted for any reason, the following error message could appear when the user tries to manually connect to GPRS using the connectoid:

"The answering modem has disconnected. To check your connection settings and change them if needed, tap Settings."
