After carefully reading posts for the last 2 days I successfully flashed to the new rom. Followed advice on GPS settings and everything works great. I immediately tested the GPS on google maps and got 5 or 6 sats pretty quickly. FINALLY, weather and GPS the two things I really wanted added!! (now maybe i can leave the Touch at home)
Thanks again to everyone for the helpful advice!
p.s. I used this guide.
