[Rehabilatator]

I just received a replacement tour and back up my old info....then i tried to wirelessly update the new phones os to 5.0 seeing as how it came with 4.7 installed....anyway as the phone was 89% done with backing up the info it just froze and said uncaught exception...and all of my data was erased and after a battery pull the device automatically starts to wirelessly back-up.....well is there any way to stop it from auto updating???
