On my jailbroken ios6 device, I like to personalize my app icons. With most apps, this is no problem--I just find the icon png file (which may be called icon@2x~iphone.png or some such) and replace it with my own .png of the same size. But I've got a WebClip app for which I can replace the icon, but as soon as I invoke the app, it changes the icon back. I've tried toggling and also deleting icon entries in the info.plist file, but that file too is always reverted to its original state as soon as I leave the app. I went so far as to change the permissions on my icon.png file to 444 (read-only), assuming that if the app didn't have write permission, when it went to overwrite the icon, it would at least hang. But it didn't. What gives???
