you will loose all the information on your phone so u have to back it up somehow (i use PIM Backup) or move your pics/music to a card. When you do flash to the new sprint rom (which you need to do to get GPS), after you upgrade the bootloader first, do not let the sprint customizations run. When its done and it gets to the screen, "tap here now to ...blah blah," do not tap, and just run a kitch or a new rom. good luck
