Some afterthoughts:
This would have been a very wonderful release, censorship aside, had it been handled with a little more care and attention to the market it got released in.
Had they took into consideration the iOS market, I'm sure NBGI would have found more success in this if they released one version, with just iM@S allstars songs bundled in. (Of course, there's the issue of which episode to play in the beginning, and the whole different idol units in Shiny Festa mode, but it couldn't have been too hard of a task to make that work) Then, charge for individual idol songs. Or sell them as a pack for every idol or something. Instead, just like the PSP version, the iOS version oozes of laziness, and reeks of missed opportunity.
