Ok well I did this first with the calculator and it worked fine. I copied the calculator.apk to my desktop replace the png image for the icon witout unzipping it just leaving it up in winrar the replacin image with another from my desktop with tth esame name. Well I tried to do this for taskkiller and a few other market apps so I can have my full theme with all of my apps but its not workign for some reason. I was sure if I am breaking the signing or what its doing but once I replace the png file it wont install. Now I do have the signing tool but not java because I heard yoru not suppose to sign things with windows 7 which I dont know how true that is but one is there a way besides better cut to change my icon because I want the icon in the app drawer changed also. If not can I download java and sign my apks so I can reinstall them? Also I tried to replace the png file with ninja morph and that wouldn't work either once I do that app dissapears?
