Howdy!
Unity 3D has announced that going forward all their mobile development licensees will be free (these have retailed for years at $400/pop occasionally having a free period).
Upon the release of their Windows Phone 8 and Blackberry 10 versions these will be free too.
This really is a great mobile development platform for starting out at building your own games + applications, its basically the essence of "code once, run everywhere". You can program in either C#, Javascript, or Boo (Python) across all platforms.
