Sure, some of the latest Samsung Windows Mobile phones like the Omnia II aren't yet widely available but nevertheless, you might want to start to develop for or porting your existing application to it already. If so, Samsung has just released its Windows Mobile SDK 1.2 which offers APIs to use advanced features unique to Samsung phones. You might already have experience using advanced capabilities featured in the Windows Mobile APIs, like GPS, Bluetooth, or multimedia support. In addition to the Microsoft Windows Mobile APIs, you can use Samsung APIs to access phone features such as the accelerometer, notification LEDs and haptics feedback.

Version 1.2.0 of the SDK includes new APIs for FM Radio and dual camera functionality as well as it also includes support for three new phones: the GT-C6625 Valencia, the SCH-m490/m495 T*Omnia and the GT-I8000 Omnia II.
It's now available as a free download from Samsung's Mobile Innovator developer website.
