I'm a freelance Flash game developer and I just started building iPhone apps a couple of months ago. I'm currently being contracted to build a fairly major app for a friend and hoping to get some other projects soon (the rent needs paying!)
I'm gradually moving over from Flash games to full-time iPhone development as that's where the "new money" and work is, and I'm also enjoying Objective-C more as it harks back to my "good old days" of C++ programming in the 80s and 90s.
