Tap-no-Joy as Apple get tough
Apple say no! The Tapjoy API (used in Gun Bros etc for monetisation) is no longer allowed in iPhone games. I can understand why, but surely there is a comprimise to be had somewhere? I love freemium games and this worked really well. I certainly purchased a few games of the back off their system.
This article explains it all very well:

TapJoy's system definately made me laugh at one point as I questioned what content I really would download for two free warbucks?...
And just to cheer you up again...
Love this game: Checkpoint. Particular fan of using your own dead body as a platform. Give it a go.
