GTX seems to be one of many hit mods that have been developed in our forums this year. In a very recent post by XDA member fjompa , the dev asks to begin development on GTX Icons. Now, while some people not familiar with the whole concept of GTX this might seem weird, but this famous theme has extensions in just about everything from lock screens to sms packages. The original poster only has one icon, but I am sure with our big community we can get many more icons by the end of the week.
If you want to help him out, head over to the thread and contribute to the development.___________________
