PPCGeeks - GPS with Latest Official Verizon Rom...Jumpy Coords in TomTom and iGuidance

I upgraded my touch to WM 6.1 about a month ago, and I haven't had too much luck getting the GPS to work right. The GPS works great in Google Maps, but when I try either TomTom or iGuidance, the coordinates jump all over the place and I am never able to get a lock. (IE - one second it will say my coords are -71w 52s, and the next it will say 63w 23n...Really weird)

I did install the Valhalla fix, but I don't know if it worked or works with the latest rom. Does Google use AGps? I'm wondering if this is why Google works and the others dont? I saw some others over at xda experiencing the same issue, so I know I'm not the only one having problems.

Has anyone found a fix for this? I'd rather not switch to another rom if possible since everything else is working good, but I might consider it.
