Comex and his crew has updated JailbreakMe to version 3.0, a handy browser-based jailbreak service for all iDevices including the iPad 2 running on running iOS 4.3.3.

To guide us with the latest update of JailbreakMe, the devs has also posted a lengthy Q&A about jbme3.0:

Q: Which devices and firmware versions are supported?
A: In this initial release, the following configurations are supported:

iPad1: 4.3 through 4.3.3
iPad2: 4.3.3
iPhone3GS: 4.3 through 4.3.3
iPhone4: 4.3 through 4.3.3
iPhone4-CDMA: 4.2.6 through 4.2.8
iPod touch 3g: 4.3, 4.3.2, 4.3.3
iPod touch 4g: 4.3 through 4.3.3

Q: Do the holes discovered by @comex put my device at risk?
A: Yes. We recommend installing “PDF Patcher 2” in Cydia once you’re jailbroken to eliminate this risk (any firmware version).

Q: How does jbme3.0 differ from the existing jailbreaks?
A: jbme3.0 is entirely userland-based, from start to finish. The A5 chip in the iPad2 has no iBoot or bootrom-level exploits yet, so tools like redsn0w, PwnageTool and sn0wbreeze can’t use the limera1n bootrom exploit to inject the jailbreak. Even for those devices where limera1n works, jbme3.0 injects the jailbreak with a userland exploit.

Q: If I’m already jailbroken on the latest firmware, is there any advantage to jailbreaking again?
A: No, but you should consider showing this to your friends! Spread the jailbreaking fever.

Q: Are the holes exploited by jbme3.0 closed in iOS5?
A: The holes still exist in the iOS5 betas, but they’ll almost certainly be fixed by the time iOS5 is public. However because the iPad2 had no public jailbreak yet, it probably wasn’t worth waiting until the fall to use them. If history repeats itself though, there will be more holes and exploits.

Q: Will I permanently lose the jailbreak if I need to restore my device?
A: For all except the iPad2, saving your SHSH blobs should let you always restore your device to iOS versions where this jailbreak works. The iPad2 is a little more complicated. If you have a wifi-only iPad2 and saved SHSH blobs, you’re in good shape. But if you have the GSM or CDMA iPad2, you won’t be able to restore to 4.3.3 or lower once Apple stops signing its baseband. There are a few ideas that might work to get around this limitation, but for now it’s best to assume there’s no going back to 4.3.3 once 4.3.4 is out for iPad2 GSM or CDMA owners.

Q: I heard this new unionfs stuff is dangerous?
A: Define dangerous :) Seriously though, although unionfs is a huge improvement to the install time of the jailbreak, it is brand new code and there is the possibility something will go wrong. Just keep regular backups of your media and content and you should be fine. If there are any problems, they should appear within the first few days, so hold off and let “everyone else” test the waters if you’d like.

More info about the release can be found at the sorce link below. Last May, the iPhone DevTeam released an untethered jailbreak for iOS 4.3.3.

What you should do is make a DFU ipsw. There's a way to open it, move a few files around, use it to restore, and that puts it into dfu mode. Then, you have to downgrade to 3.1.2, jailbreak with Blackra1n, then create a custom pre-jailbroken 4.2.1 ipsw with Sn0wbreeze or Pwnage Tool. pretty much upgrade from a jailbroken 3.1.x software to 4.x.x. I had the same issue, but I had the balls enough to take it apart and replace the ribbon cable inside.

Here's a link to make an ipsw that puts your phone into DFU mode:

invalid checksum error means the server is getting hammered.
