iOS 7.0.6 is the latest version of the operating system for our iDevices, Apple Lossless Audio CODEC (ALAC), launching it just a few weeks ago to solve a very important security bug that allows any hackers to steal your login data in websites and more. If you don't have jailbreak, then the update to iOS 7.0.6 it is absolutely necessary and will ensure that the data in your terminals will always be protected, making this update extremely simple through the system OTA Update, all the data in your terminals remaining intact.
If you jailbreak, then performing the update involves restoring the jailbreak and reinstalling the tweak/applications from Cydia if you haven't saved them, but if you have saved them with PKGBackup, then you will be able to reinstall them immediately after the update. Practically however you look at the situation, the update is very easy and even if you have a patch on jailbroken terminals that applies the security changes implemented by Apple, it never hurts to have the latest version of the operating system, especially as it can be jailbroken using evasi0n7.
launching iOS 7.1 is imminent, and in a few hours after the publication of this version of the operating system you will not be able to install anything but iOS 7.1, so think about it if you want to be able to benefit from jailbreak on iOS 7, if you haven't installed it yet.
