On my 3650, I could set up an access point called Bluetooth set for GRPS, no
gateway. Then, I could set an e-mail box up in messaging to use this access
point. Then, connect a serial port from the PC to the phone with mRouter
running, and Messaging would access my e-mail over the bluetooth connection.
I can no longer do this on the 6600 - instead, the phone tries to dial the
GPRS access point and I get the error 'Invalid access point'.
I could do a similar thing with AvantGo, Opera etc. i.e. if a Bluetooth
connection was there, it connected over that but that also appears to be
nobbled on the 6600.
