I have moved to a Sendo X from a T610. With that phone I could connect from my Tungsten T3 via Bluetooth and pick up a GPRS connection. I can do this from my laptop (not that it wasn't quite fiddly and delicate to do) but have had no success with the T3, despite trying at least to mimic the settings ie (for Orange)
at+cgdcont=1,"IP","orangeinternet"
at*99***#
But the connection does not complete.
Anybody been successful with this?
