I'd been having a few issues with my iPhone 4 (one of the main being that apps wouldn't open and turning it off and on again to remedy this resulted in me losing all of my contacts in my address book). When attempting to restore my iPhone, it sometimes causes my computer screen to become distorted and freeze my computer.
I'd been on iOS 5.1 (?) for a while (having put of updating it due to lack of space) and my brother suggested updating to the most recent iOS. I did this, but afterwards, my phone said it had to reset back to factory settings. I reset it, but when I went to restore my backup, I got the message “iTunes could not restore the iPod 'NAME' because the backup could not be saved on the computer.” Having looked around, people seemed to suggest that I needed to clear some disk space on my laptop. I've done this, and I have 217 GB free, so I can't see why this should be an issue now, but I'm still having the same problem.
Can anyone suggest a solution?
