If you thought people jailbreaking on-display iPod touches and iPads at Apple Stores was cool, this you’ll find even more cooler.
If you've been trying to figure out a way to jailbreak your iPhone 4 or 3GS running iOS 4.3.3 and none of the existing methods seem to be working for you, try JailbreakMe 3.0. This new method allows you to jailbreak your device by simply navigating over to a webpage.
The iPhone Dev Team released Redsn0w 0.9.6rc15 to support untether jailbreak for all devices (except iPad 2) on iOS 4.3.3 firmware.
iPhone developer ih8sn0w has updated Sn0wbreeze to version 2.7 in-order to include support untethered jailbreak for iOS 4.3.3 (iPhone 4, 3GS, iPad, iPod touch) and iOS 4.2.8 on Verizon iPhone 4.
The iPhone Dev Team has released updated version of both Redsn0w and PwnageTool to jailbreak iOS 4.3.3 untethered using i0n1c’s untethered exploit.
The just released iOS 4.3.3 firmware update for iPhone 4 has been successfully jailbroken using custom PwnageTool bundles. The jailbreak though is tethered only for now, which means that you will have to boot it into jailbroken state every time you reboot.
I have just tested this and can confirm that the current latest version of Redsn0w can jailbreak iOS 4.3.3 (tethered) on iPhone 4, 3GS, iPod touch 4G/3G and other A4 based devices.
