You really should release some of your stuff Andy!
Your pirate game would be perfect! Check out "Bloo Kid 2" for an example of that type of game which has done well on iPhone.
I have two games on iPhone currently, and I'm starting to get the hang of it, so if you need any help with that (assuming it wouldn't take much work to port) then I could possible assist you.
I'm kinda avoiding Android for the time being though since the Fusion Runtime for it is so slow and poorly optimized although I do have both my games on Android as well. Their performance isn't as good as iPhone's though.
