I'm a newphag and GTA got me into it. Been playing GTA V since release. I used all the popular glitches and whatnot from Launch to February 2014.
I used to do stuff like editing vehicles in gamesaves then glitching online to store (Franklin's Buffalo <3), the old school simple ass money glitches, etc.
Used DNS' when a little bit before they became super common. After it got patched I came across a video of BadChoicesZ RTM tool on GTA, spent a good few weeks learning about CFW, how to get started, what a good price for a 3.55 PS3 was, went shopping, and got one in February 2014.
