when i try and restore my iphone and i get to the step where it asks if i want to set up a new iphone or restore a backup, i click restore backup but then after a few seconds i get an error that says something like problem restoring backup and then i have no other choice than to let it write over my old backup with this new backup. Why am i getting this error? is there any way to fix it? sooo annoying. any time i have to restore my backup is completely useless. have to redo settings, lose my camera pics, texts, notes, weather presets. UGH this sucks
