I'm currently looking for a tracker that specializes on content for mobile phones and tablet PCs. If you were around the torrent world more than a year ago, you might remember PimpYourMobile (RIP). A site like that is what I want. I'm interested in the following:

Android content
Symbian content (all versions)
iOS content
Windows Mobile content (older versions too)
application packs for older phones that have "unique" operating systems

content=applications, games and themes (where possible)

If you have any ideas, let me know.
