iOS 4.3.4 IPSW Available – Update Online Or Download IPSW And Restore Offline via iTunes [Direct Download Link]
Apple has just released iOS 4.3.4 Firmware for download. This new iOS 4.3.4 addresses the PDF exploit in Mobile Safari that was used by JailbreakMe to jailbreak iPhone, iPod Touch, and iPad the easiest way.
This new iOS 4.3.4 release notes the new updates are meant for “security fixes,” and as far as the gesture goes, this new release seems to be primarily meant to block untethered jailbreak via the previously one-install popular JailbreakMe.
The release note further states:
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.
You can download iOS 4.3.4 online by just going to iTunes and upgarding to IOS 4.3.4. This is really time consuming though, and the process is very slow.
Alternatively, you can first download iOS 4.3.4 firmware update from direct links below and manually restore later (quick 5 mins installation) either via sites like Felixbruns or via any direct link below:

NOTE: JailbreakMe 3.0 had been a real easy jailbreaking solution that allowed devices to be jailbroken and install Cydia just by visiting the website, JailBreakMe.com and installing Cydia that would open door to another world of iOS applications.
So if you rely on JailBreakMe 3.0 to jailbreak your device, just stay away from this update.
