iOS 4.3.4

Should I Update my iPhone to iOS 4.3.4 / 4.2.9 Firmware?

Many iPhone owners are wondering whether they should follow the iTunes prompt and update to iOS 4.3.4 or not. There are a few questions you might ask yourself before making this decision to help determine if the 4.3.4 (4.2.9 on Verizon) firmware update is for you. Skipping the update leaves your device at iOS 4.3.3 or earlier, which could be useful down the line.

On Friday, Apple launched iOS 4.3.4 to patch a vulnerability that allowed hackers to remotely take over iOS devices. Unfortunately, this security risk was also the same PDF exploit used by Comex to release JailbreakMe 3.0 a little over a week ago. Not a big deal if you stuck with iOS 4.3.3, but for those of you who didn't get the memo, there is a savior in the form of a tethered jailbreak. Not as good, but better than nothing.
