BiteSMS is really my favorite jailbreak app. It is accorded with advanced features than iPhone’s native SMS app. Recently, the developer of this app has released its version 7.0 Beta which is meant for jailbroken iOS 6. Everybody has their own personal reasons for doing so, and although I do find tweaks such as SBSettings and Springtomize to be incredibly useful, the primary reason I regularly jailbreak my iPhone is for a text-messaging enhancer by the name of BiteSMS.
How To Install BiteSMS 7.0 beta on iOS 6
1- Download, install or update your iPhone to iOS 5
2- Jailbreak your iPhone iOS 6 first
3- Install Cydia app
4- Add following repository in Cydia:
5- Search BiteSMS
6- Find and install BiteSMS 7.0 Beta
Since this version is still a beta, expect it to be buggy. If you cannot deal with a few bugs (unlikely, if you’re running iOS 6 with a tethered jailbreak), then the developers suggest you stay away for the time being, and wait for a more stable release. Those who are new to the jailbreaking scene, it’s highly recommended that you give BiteSMS a shot, as it is a near-perfect replacement for the stock Messages app which Apple ships with iOS.
