Yes it's here - and in Steve Job's cash cow AppStore so run out and buy it now.
I've been impressed by the Raptor Rage team as they struggled through a porting exercise because of a last minute memory leak in Adobe's iPhone Packager - unable to be fixed as of AIR 2.6. Their solution was to use Monkey as a cross-platform solution with the added props that it was home grown in New Zealand.
I can easily recommend this game - especially if you liked the old classic Pea Shooting Pete. So as always if you have exactly the same taste as me - go get it.
