Hi guys! I have an iPhone 4s running version 5.1.1 (9b206). It is factory unlocked. Now i am desperate to update to the latest version 6.1.2. It is the latest Version of the iPhone. But I have alot of stolen apps which I dont want want to download them again. It took about 2 days to download one game. However I dont know what to do. On youtube or google they say backup. Now everyone has its own way, i dont know which one to follow. So i want to ask that how to backup these games and how to get these game back on my iPhone. And that if i upgrade will it affect anything to the factory unlock???
please just explain me how to do these step by step!!
