I was going to change out the middle icon for my helix launcher but when I went into the system/app to grab the launcher I noticed it said launcher.apk and this is the stock 5screen launcher that came with the rom and am using helix which I downloaded from the market so if the one that came with the rom is in system/app folder as launcher where is my helix launcher.apk located Also from what I understand Imust resign market apps.Now if I change the apk extention to .zip it allows me to open the file up and look at it. If I dont extract anything just replace the image with one from my comp I shouldn't have to resign correct? but if I do extra the contents I need to resign. now since i have to change the file extension to .zip to be able to open and look at the apk does that break the signature? or do I need to extract the files to break the signature?
