they are part of the gappsbackup.zip available from my site here:
linkey(link is also in first post). You will have to extract the contents of this .zip file somewhere, then filter through its contents for the .tar.gz archives you want(there are also .apk.gz files which hold the backups of the gapp .apk files).
If you don't mine my asking, are you any good with android hacking? lol we could use a few good android dev's right now(I think we have a few but more is always better
)
