In addition to offering songs from iTunes without DRM restrictions, Apple (AAPL) also plans on selling songs to iPhone users "over the air"-that is, you can buy them directly from your handset, from wherever you are. I'm told that Apple has struck deals with the major labels to start selling songs to iPhone 3G owners sometime this spring.
If you own an iPhone (or iPod Touch), chances are you've played Tapulous' "Tap Tap Revenge," a touch-screen and motion-controlled riff on videogaming's booming music genre. Apple recently revealed that "Revenge" is the third most popular free application on its App Store, and Tapulous Chief Executive Bart Decrem says half a million people play it every week since it debuted last summer.
