I have done a backup to my computer for my iPhone 4 (version 4.3.5)
Had bought an iPhone 4S (version 5.1.1) and had connected my 4S to my computer and tried to restore the backup but failed.
Did anyone experience this before and how do u solve it? Thanks in advance!
See this one:
Have a new iOS device and need to move your previous backup onto it? Follow the steps in How to transfer your backup from one iOS device to a new device.
If you update the new phone and try again, it should be able to restore from the backup. If that fails, the backup might be corrupt.
