    I have no reason to jailbreak currently but was wondering what procedure to use in order to ensure I could jailbreak it in the future if I wanted. Could I download the current iOS firmware and backup my current SHSH blob without jailbreaking? Is tinyumbrella the way to do this?

    TinyUmbrella is what you want. No need to jailbreak to save blobs.

    I'm confused. I have a GSM ipad2 and just ran the latest TinyUmbrella to save SHSH for 5.0.1. I saw in another thread people saying I need to upgrade to 5.0.1 now if I want to ever have it because SHSH are "useless" in IOS5. However, I saw on the TU website that it makes APNonce requests, although I don't know if that generates a separate file or that's just included in the SHSH file that TU creates.

    I'm on 4.3.3 right now; I haven't jailbroken my ipad in the past but I guess I like having the option. However, I'm not sure yet about whether I want to upgrade to IOS5 right this second as I have to check app compatibility. Newer versions of some of the apps I use have design changes I don't like, or obnoxious bugs, so I have left them on older versions. I haven't had time to check everything for compatibility so I'm not sure I want to rush in to upgrade to IOS5.

    In any case, do I need to upgrade now or can I wait and upgrade to 5.0.1 later, given that I just saved SHSH (I guess w/ AP Ticket???) in TU?

    If you've saved the 5.0.1 SHSH Blobs in TinyUmbrella, you do not need to update your iPad now. At a later time, if Apple has stopped signing 5.0.1, you can use TinyUmbrella and your saved Blobs to trick iTunes into restore a 5.0.1 IPSW onto the iPad and then jailbreak with Absinthe.

    Okay! I don't understand what some of the posts mean when they say that a bootrom exploit is needed or some other sort of thing in order to be able to use stored blobs for IOS5 on a GSM ipad2. Other places I look, it seems as though this isn't the case. It's very confusing!

    To reuse saved iOS 5+ SHSH blobs on an A5 or newer iDevice a bootrom is needed. The only A5 iDevice that can reuse saved SHSH blobs is the WiFi iPad 2 and 4.3.X SHSH blobs.
