As reported earlier, the Cupertino giant has just recently released the new iOS 4.3.4 for the various iOS devices, and along with this, Apple has also released the iOS 4.2.9 for the CDMA based Verizon iPhone 4 that patches the PDF exploit in Mobile Safari that has been exposed by the recently released JailbreakMe 3.0 tool by Comex. Let’s have more information on this newly released iOS 4.2.9 firmware of Verizon iPhone 4 from below with the download link.
Well, if you want to keep your untethered jailbreak secure, then, just keep distance from this version as far as possible. Just be sure that you have installed PDF Patcher 2 from Cydia that actually closes the PDF hole after untethered jailbreak providing you the same effect of iOS 4.2.9 on 4.2.8 with fill untethered jailbreak.
And those who really want to upgrade to the new firmware, then, just connect your iPhone to your PC or Mac and start iTunes. Once prompted for update, click on “Download and Install” (Mac OS X) or “Download and Update” (Windows) to get on to the new 4.2.9 firmware.
