I have Sprint TP2 and my GPS is immediate as well (stock gps with no regedits). After softreset google maps takes about 20 seconds to lock, then its instant from then on.
I did try a few different tracking programs, and VisualGPSCE seemed to cause a com port issue (it has to get direct access instead of using the windows driver), and then I'd get gps issues where it wouldnt lock and use cell towers, but soft-reset fixes that. I've since removed VisualGPSCE and now I use tracker.cab (found on xda) to save my bike rides with no issues and great accuracy.
