Battle Online is the only one I can think of. Then again you have the official Bomberman apps, but they're just junk.
I have Bomberman 2 on iOS and I have to say it does suck, especially compared to Bomberman on my DS. I wouldn't buy Battle online for $4, though.
Wow, it went up in price?! It was 1.99 for a long time. I'm just surprised cause' it didn't really receive anything new, besides a name.
