I recently Jailbroke my iPod Touch, and as you might have guessed, I’ve downloaded many applications. The problem is, some of the applications either have really strange metadata tags, or no tags at all. Therefore, there isn’t a name, rating, genre, etc. The display name for the application was also really messed up. iTunes won’t let you change these tags, and most internet forums tell people to download some app from Cydia to do this. Anyways, I found a way around this, so you can edit the tags for the .IPA file directly. To do this, you’ll need several programs: - WinRAR - Plist Editor - iTunes (Duh) A Couple of Things to Note: - The programs were compiled for a Windows XP computer. If you’re on a Mac or something, you’ll need to find different programs. - Back up your original .IPA file, just in case something goes wrong. - Downloading pirate apps is illegal, so don’t do it. - On my computer, Notepad can kinda work with the .PLIST files to some degree, but I suggest you use Plist Editor. Step 1: Install all these programs, if you don’t have them yet. Open up the .IPA file (your application) with WinRAR. Usually, there is one folder and two files in it. Extract the file iTunesMetadata.plist. If it isn’t there, I have a uploaded a simplified one of these to zShare, available here. There were over 100 lines of code in the original file, so I did you a favor and narrowed it down to the important ones. Step 2: Open up iTunesMetadata.plist with Plist Editor. Edit the tags in this file as necessary. If you download the simplified file I uploaded (Step 1), you’ll see that I’ve deleted many tags. I deleted stuff like copyrights, download date, and version number, but kept more relevant stuff like the name of the seller, whether it’s a game or application, the name of the game, the age rating, and the genre. In my document, I have replaced these tags with what you should include, e.g. where you should put the seller, I have put ‘(Seller)’, so just change the value in between the <string> thingies to the desired display name. Change anything in parentheses. When you’re done, replace the original iTunesMetadata.plist file with the edited one. Step 3: Now, you’ve successfully edited the tags that show up in iTunes. However, you still need to edit the display name (the name that shows up on your iPod Touch). Open up the .IPA file again, with WinRAR. Open up the ‘Payload’ folder. There should another folder. The name varies based on the application, so I can’t really specify that. Just open whatever folder you find in ‘Payload’. Now, there should be a bunch of random files, with lost of funky extensions and stuff. Ignore then, and look for Info.plist. That’s the file you need to edit. Open it up with Plist Editor, and look for this line of code: <key>CFBundleDisplayName</key> Below it, you should see something like <string>(Original Display Name)</string> Change the value in between the <string> thingies to the desired display name. Replace the old Info.plist file with the new one. Step 4: All done! Just add your new .IPA file to your iTunes library, and everything should be fine. Hope this helps you. EDIT: I just saw the other tutorial about application name changing, but I would like to add that this tutorial differs from the other, as a different technique is used here. I am showing how to change the .PLIST files, thereby editing the source material of the application metadata.
