Not really sure if this will catch on or not but it's out tomorrow for the following devices: iPhone 3G, iPhone 3GS, iPhone 4 and iPad
After mentioning it in another thread I received 4 friends requests from people on here so there does seem to be some sort of interest in it even although there aren't yet any compatible games or Achievements.
