Open Source Software for Mobile Phones

Rhomobile’s open source mobile application framework Rhodes lets you quickly build native mobile applications for all smartphone operating systems: iPhone, BlackBerry, Windows Mobile, Symbian and Android. Mobilizing with Rhomobile consists of creating a RhoSync source adapter, generating an application with Rhogen, editing your HTML templates and Ruby controller actions and building the resulting application in your mobile development environment of choice. These are true native device applications (not mobile web apps) which work with synchronized local data and take advantage of device capabilities such as GPS, PIM contacts and camera.
