Attention Developers! Rhomobile’s mobile application development contest can put $10,000 in your pocket. The contest is promoting Rhomobile’s Rhodes framework, which allows developers to write native applications for the iPhone using HTML and Ruby.

After you’ve written your iPhone application, the Rhodes framework will allow you to run the same application on BlackBerry, Windows Mobile, Symbian and Android mobile phones!

Your submitted application must run on at least two mobile device operating systems. First prize earns the $10,000, and additional developer prize packages will include an iPhone 3G (16GB), AT&T (HTC) Fuze with Windows Mobile, BlackBerry Storm, Nokia N97 and G2 Google Android phones.

Full contest details are available Here. Developers have until April 15th to Register, and until until Sunday, May 24, 2009 at 5pm PST to submit your final application.
