I have iMovie installed on my 3gs, with the plist mod, and i updated itunes to 10.3. I didn't sync with iTunes after installing imovie and before updating from 10.2.x. But now, when i sync, it keeps asking me to authorize the comupter for purchases on the iphone, so i put in my password, hit ok, it takes it, and asks me to authorize again. I tried removong it and installing through iTunes but it says it's not for that phone. Is there any way to get past this?
