    Hi all,

    I am completely unknowledgeable about jailbreaking other than jailbreaking an iphone 2G from a few years back but I'm sure that information is obsolete to me now. I downloaded my old copy of Tinyumbrella and plugged into see what my iPhone 4S would be and while Tinyumbrella showed the model # and name of my old phone, my new 4S shows up as "MD236LL/A - INVALID". Why does it say invalid? I had to have my phone replaced due to faulty camera at the genius bar. Could that be a reason? Is my phone unlocked?

    Tiny umbrella doesn't work on iOS 5, and seeing as the 4S can only run iOS 5 or higher, tiny umbrella is probably throwing back errors.
