    Hi all,

    currently have an iPad on 3.2.1 jailbroken. Can anyone guide me if I can upgrade to 4.2.1 and jailbreak it (untethered)?

    Thanks!

    Welcome to the forums.

    Right now the untethered Jailbreak is......troublesome at best. Search around the forums here and you will find that out for yourself.

    For now all I can suggest is that you upgrades in increments. Upgrade to all of the betas one by one, jailbreak, and save your SHSH Blobs in each beta. You will NEED the Beta 3 one in particular in order to use the current untethered jailbreak ( which as it stands right now....is a failure until they release the official one )

    I wish you good luck.

    Not the best advice digikid. There is no advantage at all in upgrading incrementally using the beta firmwares. You are misunderstanding the process for saving blobs. All you will do is waste the time of the OP.

    Firstly, there are no blobs for beta firmwares OTHER than beta 3 which was a special case (it was supposed to be the release candidate).
    Assuming the OP started saving blobs through Cydia with 3.1.3 then they can retrieve all their blobs from Cydia using tinyublrella. It is irrelevant what firmware you are currently running, and you cannot generate blobs for your current firmware if Apple are no longer signing them. He either already has blobs or he does not.

    If you did not save your blobs (you can tell by looking at the top line in Cydia. It will tell you what it is storing for you) then you are out of luck and can only get 4.2.1 at the moment.

    The tethered jailbreak is also not as bad as some people are making out. I certainly wouldn't' describe it as troublesome for someone that is comfortable with jailbreaking devices.
    Whilst I started with the position that I would not recommend it a couple of months ago (because of my prior experience with a tethered iPhone jailbreak), in practice I have only had to reboot my iPad twice and therefore the tethered nature of the jailbreak has been almost imperceptible to me and many others. I would now recommend it.

    The tethered jailbreak itself is bug free. That is not to say that Cydia apps have full compatibility with 4.2.1 yet, however the vast majority do.

    Hope that helps.

    so if i upgrade from my 3.2 to 4.1 and do the tethered break, all i have to do is not restart unless im connected to a pc? Is there a guide for the tethered break?

    Yes, u will have to repeat the jailbreak process everytime u poweroff ur iPad. My entire Youtube channel is dedicated to the iPad. Your cydia apps will no longer work and cydia will either be a white icon or missing if u power your ipad off with a tethered jailbreak. Personally, I don't know anyone that ever turns the ipad or iphone off

    Yes, but it's 4.2.1 on the iPad. Not 4.1.
    See the dev-team blog or iclarified (or iph0ne27's you tube channel) for guides.
    Basically you must update to stock 4.2.1 then run redsn0w through a couple of times...

    If you upgrade and jailbreak you will lose nothing.

    Even if you were to do a clean restore on 4.2.1 and set up as a new iPad, you can always re-sync your apps and books from iTunes. You would only lose application settings. That is the beauty of iTunes.

    I have been running 4.2.1 jailbroken since it came out and I have had no problems. All of cydia's apps work but the ones that change things like makeitmine don't work. I would recommend it though.
