I have the new ipad with cellular, it's OS is IOS 5.1.1 and it's jailbroken. But now i need to unjailbreak it because i think i am having problem with my network being intermittent and sometimes my camera doesnt focus. Now, i tried to do it with your video using tiny umbrella, but iTunes says that THE FIRMWARE I DOWNLOADED is not compatible. This is the file i downloaded 'iPad3,25.1.19B206Restore' i dont know if i am doing it wrong or it is impossible to restore jailbreak 5.1.1. To unjailbreak 5.1.1 if it is impossible, i might just upgrade to iOS6. Thank you in advance.
Unfortunately, Apple does not provide iOS 7 for the iPad 1, so you cannot visit an Apple site and receive the iOS 7 update. At this point, your software is listed at iOS 5.1.1 because it is the last version of iOS provided for the iPad 1.
