I downloaded ios5.. and when i hooked up my phone to itunes (yes i have 10.5) it prompted i have not transferred some purchases to my iphone.. i clicked continue. it said as a part of the update it is going to backup everything on my phone. I press okay. it takes FOREVER to move a cm (about an hour) and then eventually the loading box just disappears as if i never tried to update.. what can i do?
