A few minutes ago Apple released iOS 4.3.4 via iTunes! This new version of iOS blocks the jailbreak solution jailbreakme.com used to jailbreak iPad 2 tablets. Apple blocked the vulnerability that allowed exploiting iOS using PDF files, so be very careful NOT to UPDATE, especially if you have an iPAd 2. If you accidentally updated to iOS 4.3.4, then immediately restore to iOS 4.3.3 because there is a chance that you will be able to do this for a few hours!
Here is the changelog for the new version of iOS plus links through which you can download it:
Impact: Viewing a maliciously crafted PDF file may lead to an unexpected application termination or arbitrary code execution
Description: A buffer overflow exists in FreeType's handling of TrueType fonts. Viewing a maliciously crafted PDF file may lead to an unexpected application termination or arbitrary code execution.
UPDATED: Here you can read about how it affects iOS 4.3.4 jailbreak or DECODE.
