This was just posted via Capcom's site. It's a great game regardless what platform you play it on, but $5 is probably the cheapest price at the moment. The iTunes summary page mentions that it includes all five cases from the first DS entry. I already own the DS version, but I still recommend trying this game out if you don't own the Nintendo handheld.

Sounds great!

If you never played Phoenix Wright before GET IT NOW!

huh. I'm surprised they managed to get the fifth case on there.
 
The Wiiiware release didn't. Which is a huge shame, seeing how that's one of the best.

I'm downloading it now. I have already played it on ds, but for 5 dollars it seems worth playing again. 
 
Update: I played the first case, and it seems like a pretty good port. The touch controls work pretty well, and while the picture is pretty small, it is sharp and good looking. If you haven't played the game yet, and you have an iphone, I definitely recommend checking it out.

Sold! I've played it on the DS too but I love to support games like this so I grabbed it on my touch, at that price I just couldn't pass it up!
Anyone on the fence or who hasn't played before I can only say give it a chance, it's a slow paced game but it's a lot of fun.
 
If only the real judicial system worked like this... then again, to be honest I'm not sure if that would be good or bad! 
Actually no, it would be awesome.

Getting now!
