You might also want to consider Forum Runner for the iPhone - that currently works with phpBB forums, so you may find it works "as is" with RetroBike as it stands now?
I'd recommend Forum Runner as it is somewhat more stable than Tapatalk, although I use both for various forums, Forum Runner doesn't crash as often as Tapatalk does!
