Marmalade is a cross platform SDK that allows developers to create apps and games in Visual C++ and have them run on multiple platforms. The platform used to be called AirPlay but now referred to as Marmalade, their reach supports Apple iOS, Android, Symbian, Bada, WebOS and now the BlackBerry PlayBook in beta. Marmalade also supports all C/C++ standard libraries so you can reuse existing C++ code or repurpose Objective-C code. Most developers seem to be making games on the Marmalade SDK such as Need for Speed Shift and Studio Light Rigger, some snapshots below!

I would recommend that if you’re a developer, go check it out and leave some feedback for others to know whats good and whats not.
