A tweak for iOS 5 that merged together conversations from the same contact in Messages. I am open-sourcing it now to give others a chance to look at the code and potentially work on updating it to the latest version of iOS.
Disclaimer: I wrote this code as a beginner in 2012 and as such it is extremely ugly and monolithic. To anyone trying to understand what in the world this code does, I'm so sorry.
This is an iOSOpenDev project; you'll need to install it to compile this project.
