Trying to manually mod my iPad, and I've been able to modify the iPad's native applications. However, for the applications I have downloaded and need to modify, the png's that I copy onto my desktop to alter are all blank. No matter what program I use, they all are blank. I must be doing something wrong. I've googled it for hours and haven't found any solution. Thanks to any one who can help! Update, I finally found this information online: What png editing program (Photoshop CS5 for example) can read these compressed png's? Update: After hours of searching, I found a great OS X application called iPhonePNGApp, it will convert iPhone/iPod/iPad Application png's to readable/editable format. If you want to simply edit/alter some app's instead of starting from scratch, it's a great way to simply copy, convert, edit and upload the new png.
