I'm trying to edit the boards in my touch grind app. I tried the winterboard method that doesn't work. Now, I'm trying the direct method by simply editing the files of the app. Can anyone tell me how I can change the .ipa app to a file that I can mod, *and then change back to a .ipa*.I know how to get to the files by opening it with winrar in the "open with tab" and then decompress it to get to the files, but I cant find a way to change it back. Please help.
