You can't selectively upgrade with the iPad 3. If you upgrade, it will be to iOS 6.1.3.Hi, I have 2 ipad's v3 and one is on 6.1.2 and another on 5.x. Is it possible to install 6.1.2 on my 5.x ipad using some advantage of having another ipad v3 with 6.1.2 or it's impossible and now I can only upgrade to 6.1.3? thanks
