The game of see-saw between Apple and jailbreak enthusiasts has swung back to favor the latter. Earlier this month, one-stop jailbreak source JailbreakMe relaunched, making use of a PDF-related exploit to crack open what had been the latest iOS firmware update at the time. The exploit was fixed in a new patch released last week, and that patch has now been jailbroken.

That’s iOS version 4.3.4, to be specific, for the iPhone (3GS or higher), iPod Touch and iPad. There’s a detailed breakdown covering how to install the newly released jailbreak at Redmond Pie, though it’s worth mentioning that you’ll probably want to skip this for now if you’re new to jailbreaking. The process is a bit complicated and the jailbreak is actually described as “semi-tethered” (a “tethered” jailbreak being one in which the device must be connected to a computer via USB anytime it reboots). There’s also no unlock for 4.3.4, so if that’s the sort of thing you’re into then this isn’t the jailbreak you’re looking for.

Both the redsn0w and PwnageTool (available at Redmond Pie) jailbreakers have been updated now, but there remains no untethered option just yet.
