    I see. Thanks
    I am still new to iPad so I might ask silly questions like the one below. =p
    Will the apps I got from JB disfunction after I upgrade to 5.1?

    What apps are you talking about, specifically? And from where did you get them?

    If you got them from Cydia, they will be gone (because you'll have no jail break). If you got them from the App Store, they'll be fine on the new iOS.

    Yup.. those I got from cydia.. Understood.

    But now I become more confused.
    I can sync the apps I got from cydia to iTunes.. I can recover those cydia apps to my ipad (still in JB status) but all the data files inside are gone..
    I got this reading comic apps from cydia... I have downloaded few manga chapters. But accidently removed the apps during the sync with iTunes.. Then I sync-ed it back to my iPad, but all the chapters I downloaded earlier are gone.. T-T:(
    Is this how it was supposed to be? No back up data for Jailbreak apps?

    Thanks for the walkthrough. I've gone through the steps multiple times but still get error 21.

    I'm on a Mac and there's no special AV / Firewall s/w other than what's built into my router and I've updated my phone to 5.1 without problems. The iPad hasn't been jailbroken. I can edit the hosts file - no Apple IPs in there. Hardware Growler tells me it's in DFU mode so I'm fairly sure I'm doing all that ok.

    Anything else I can try?

    Thanks.

    Are you using the cable that came with your iPad? 3rd party and older iPhone / iPod cables have been known to cause problems with the restore. Try a different cable and make sure you are not connecting via a hub (connect directly into the Mac).

    Thanks for the suggestions. I've tried a few different cables - one of them must be the original - and two different computers without hubs :-(
    The only other thing that I can think that's changed since upgrading the phone is a new version of iTunes, which makes me wonder if Apple broke something. It's less than 4 months old so I guess it's a trip back to the Apple store. Sigh.

    No, you should always be using the latest iTunes. Don't know what else to suggest. Sorry. 5 years, and these rules never fail me... :(

    Thanks. Your guide worked just fine for me. I went from a jailbroken 5.01b to 5.1.1 clean iPad2.
