If you have already used Jailbreak.com to remove the shackles from your iOS device, then consider avoiding this software update unless of course you are unhappy with the performance you are seeing post-jailbreak.
The version of the iOS software that patches the PDF exploit is 4.3.4 for AT&T versions of the iPhone 4 and 4.2.9 for Verizon’s CDMA models. If you want to update your software then just follow the customary process of plugging into your computer and downloading it via iTunes.
