Sick of those hideous titles of the apps you own? Worry no longer. Well, you have to test it for me, but what I did so far produced absolutely no errors. I dont know what happens when you stick it back on you iPod/iPhone, or if you receive updates for that matter. Here is what I did.
> Find application you wish to edit in iTunes
> Right click App > Show in Finder
> Delete App from iTunes > Dont delete actual files
> Right click IPA App > Go to Get Info
> Go to Name & Extension > Change extension to ZIP
> Open ZIP file > Go to the App file
> To change iTunes Metadata > Open iTunesMetadata.plist
> Go down the list and change the Apps title, Artist Name, etc. > Save
> Change Apps title > Go to Payload > Simply change name.app (not extension)
> Once finished > Select all files in App file (should be three)
> Right click > Select Compress 3 items > Should then be Archive.zip
> Right click Zip file > Get Info > Name & Extension > Change to IPA
> Double click IPA file > Opens in iTunes > Should have no problems
> Now someone test it on their device to see if it works!!!
