I've been trying to uncrush PNG's extracted from an ipa for a while and can't seem to be able to get anything to work.
I don't own any Apple devices (except for an iPod Touch, a gift from a friend) but I want/need an app that has only been released for the iPad, I have extracted the contents of the ipa but I can't find a way to uncrush the PNG's.
Is there any way that I can do this on Windows?
I can actually use a Mac app because I have a running Hackintosh, but, it is running an older version of OS X (at least older than 10.6 but I can't check cause it crashes).
Example of crushed PNG: http://www.mediafire.com/?pe43no79aj8agsy
Any ideas?
Details on the format and a command line to "uncrush" a modified PNG is here:
