The current build of the Symbian Orbiter was built against the Symbian Series 60 platform. This includes the Nokia 3650/3660 (which is what we use inhouse), as well as several other Nokia models, such as N-gage, and phones from other manufactureres, like Siemens. In the future we will release a build for Symbian Series 70 and 80, and also UIQ (Sony Ericsson). In the more distant future we will offer a version for non-Symbian phones, like the Motorolla's which use their proprietary o/s and java.
