Hello: New to the forum and new to the Nexus S / Android World.

I have tried my best to setup my phone as Mobilicty does not have Nexus S under it's flagship yet. Hence the pop-in SIM did not work and had to configure and has started working. Proper or not i dont know but can make calls and data.

I have a GPS in the car when I go to the telephone option on the GPS unit it displays "Nexus S" and when I go to bluetooth music option it displays the "Name" I have specified. Why the difference and how can I rectify that.

At times there is a number which I see from time to time on screen (I think it's 6 digits) any idea what that number is?
