so i recently installed a rom using rom manager. I installed skyraider 3.0 rc3 with sense and everything is fine except when i use the navigation, it stays on the searching for gps or loading screen forever and doesnt work. Do u guys know what i can do to fix this without having to change the rom or unrooting?? also, if i have the free version of rom manager, does it only allow me to download one rom cause when i try to download another it says download error?? also, is it easy to switch between roms or do u have to restore the phone/reboot it and then download a new rom??
