has earlier versions available, i think(i did not have a chance to try it out, yet)
But i believe it to be .ipa file that could be manually transfered to iphone via SSH(dont know much about it, except the fact that it uses Wifi) or Diskaid( or iphone browser via USB).
Just add to the downloaded file extension ".ipa" at the end
More info on how to install App via diskaid:
