GPS & Sim Card

[penone]

So my GPS is no longer working. Have not used it in awhile and the only difference in my TP2 is that the sim card that came with the phone is no longer in the phone (lost it). I went overseas and put in a sim card from Spain (which worked great btw) and lost my original sim. This was a few months ago. Have tried all the standard solutions - made sure that the location setting was turned on, did the quickgps about a dozen times, soft reset, hard reset and nada. When I try to use sprint nav I get the weak signal error. Google Maps times out and bing does the same. Also downloaded the HTC GPS tool and that was not able to find a satellite.

So - question is - does the sim card need to be present for the GPS to work?

Thanks for any input!
