Awesome: A shiny new iOS update has just been released! iOS 4.3.4 is now available on iTunes.
Not so awesome: As far as I can tell, there’s only one change here: Apple has fixed the PDF exploit that theoretically could be used to do all sorts of malicious things to you iOS device — unfortunately, that also means that they’ve fixed the PDF exploit that more-than-theoretically allows you to jailbreak your iOS device through the ultra quick JailbreakMe site.
(Of course, you could always just jailbreak your device, install the “PDF Patcher 2” fix released on to Cydia weeks ago by Comex (the same guy that built JailbreakMe in the first place), and wait ’til Apple releases an update with a worthwhile feature or two.)
Update: For those on Verizon, look for a version number of 4.2.9 instead.
