Hello everybody, I want to upgrade my jailbroken (using spiritjb) 3.2 iPad (64g wifi) to 4.2.1. I know that this topic is quite redundant, but I found some contradictions in what I read and I want to be 100% sure I won't mess my iPad and put myself in a position where I wont be able to jb afterwise. So, here are the details of my current state: - in Cydia, I can see on the top that I've my 3.2, 3.2.1, 3.2.2, 4.2b3 blobs are backuped (they appear in green) - I used tinyumbrella to backup them too, and got the same versions backuped as in Cydia. - I have installed a fresh iTunes 10.1 in a Windows XP VM i'm running in virtualbox 3.2 (ubuntu). Also, I never connected my iPad to it. - My iPad is running springboard and circuitous (maybe irrelevant?) - My iPad disk is almost full, so I would like to remove 20Gig of photos before starting the upgrade. I don't want to do it manually, photo by photo on the iPad, and I have them somewhere else. I'm considering using the latest version of redsn0w, the tethered one. I'm aware that the untethered version is currently being tested on Mac, but I have the feeling that it's not really a problem: if I manage to get 4.2.1 tethered jb, I'll be able to switch to untethered at some point (either with a cydia package as comex suggested, either with a full re-install). I would anyway appreciate if someone could confirm (and even detail!) this point. Here are the big steps I think I should do, please correct me if necessary: - Disable automatic synchronization in itunes - Connect my ipad to itunes - Do my photo clean up in itunes - Do a backup using itunes backup --> In case of a massive crash, is the produced backup will restore my iPad in a jailbroken state, including all my apps (legit and cydia) ? - Upgrade to 4.2.1 using itunes "upgrade" option --> At this point my iPad will reboot in 4.2.1, all my apps will still be here, but I'll only be able to use the legit ones. Is it correct ? - Run redsn0w 0.9.6.xxx ; the following steps are pretty well described, so I don't think that I need any detail on this part. --> After this, my iPad is running 4.2.1 : WIN. If you feel some annoying n00bness in my post, please be kind! I'm pretty sure that a lot of people are in my case and that those "bootstrapping" steps are never described along with the JB process, which is kind of scarry. Thanks in advance!
