GPS not working

view story

http://forum.xda-developers.com – Sorry, but I refuse to give this phone up yet as I love the size, weight, etc. I unlocked this phone awhile back and through the software upgrades, the GPS stopped working (works maybe 2% of time) Any idea's if I can reflash the ROM, drivers, firmware, etc. to try to get this GPS alive again?
