I have an iPhone 4 and it locked up upgrading from 5.1.1 to 6.1 What should I do?
I have an iPhone 4 and backed it up to laptop to iTunes then tried to upgrade 5.1.1 to 6.1 and it locked up. It actually just reboots directly to the itunes logo with a USB indicator.
What should I do?
This iPhone is used by a drug rehab center and is important.
Thank you in advance!
