Hi everyone, i have a problem with my iphone. I got iphone 3gs (yeah i know that this is old phone) with 4.3.2 iOS. I need to upgrade it to ios 5.1.1 or 6.1.2 but i don't know how. When I plug my iphone to itunes it says " do you want to upgrade to iOS 6.1.3". But i don't need that because i can't jailbreak it.. Could you help me please ? Sorry for my bad english.
