GPS + data connection

[umuri]

I just finally upgraded my phone, an alltel ppc 6800, and yes i'm on alltel.
I first flashed the upgraded alltel rom, then no2chems.

The gps works, but whenever i activate it, it activates a data connection.
No "Dialing #777" icon, just the connection goes grey a bit hten white once it connects up top. "Sprint PCS" data connection.

Is this just a default name given for when it connects to itself for gps data, or is something screwy going on?
