"I just bought an iPhone 5 and every time I try to restore iPhone 5 from iPhone 4 backup, I get the error that tells me iTunes can't restore from backup. I've tried everything I know: restore the iPhone 4 and then try and use the backup, delete the backup and make a new one, restart itunes, etc., however everything doesn't work. Any suggestions about how to restore old iPhone to new iPhone would be appreciated." -- Hew, Florida
