I wish you luck. I made a few mobile games with my buddy several years ago. I enjoyed the work, but we were trying to make livable wages with it... which turned out to be quite a challenge.
If I could offer one bit of advice - start with something really simple (think Pong, a simple adventure game, or simple FPS with one gun) that is somewhat in the vein of the game you want to make then slowly expand on the feature list. You'll learn a lot just by doing the fundamentals, and you'll become more efficient as you get more intimately familiar with your SDK.
If you start with your "real" project at the outset you'll be tempted to scrap your early work and replace it with your newer, better methods. I don't recommend this. Think of your first few iterations as prototypes. By the second or third prototype you'll have a decent idea of whether you should start a new project or continue fleshing out a prototype project.
Anyway, good luck. And please update us as your project(s) progress. It's fun to watch games be developed!
