I've tried using GPS on my 8310 and was able to obtain the coordinates, however BB Maps does not show any map at all. All I see is a pin on a blank background. Could anyone tell me how to fix this?
I had a similar problem had to change the TCP setting to match my carrirer. Call your SP for that. I also had to goto options>avanced options>service books> then find the service book IPPP and delete it.
I found the APN settings for T-Mobile via google.
I therefore take back some of my reservations about the Blackberry, as this should have been highlighted by the Service provider.
