Mine's Lux DLX. I only have room for one more app! I love the x-plane series though. It's a series of airplane simulations. There's x-plane, x-plane helicopter and x-plane airliner. They're all very good and realistic. You get 4 varieties of aircraft in each app.
Adding to the answer above: Yes, Shazam sounds like a very good program. I haven't downloaded it though because I don't need it.
To the answer below: It's called iPint. I like that one as well. I've got it.
The bad thing about Fieldrunners is that they've only got 2 levels and I finished them within a week of getting it.
If you've jailbroken your iPhone, you can get free apps from www.appulo.us. If you haven't, you can't get free apps. Mine's jailbroken.
