problems with gps and cellular south radio?

[ou2mame]

i have a sprint tp, and with the cellular south radio, i can't get a gps lock. i left the phone on with garmin running, and 45 minutes later it still didn't have a signal. tomtom7, amaze, and google maps don't work as well. with the telus radio it works fine, same with sprint's 1.12.34. anyone else have problems like this? the cellular south radio works a little better in my basement than the rest, but i can't use gps with it apparently.
