Java

The dominant mobile software platform is Java[citation needed] (in its incarnation as "Java Platform, Micro Edition", "Java ME", or formerly "J2ME" ). Java ME runs atop a Virtual Machine (called the KVM) which allows reasonable, but not complete, access to the functionality of the underlying phone. The JSR process serves to incrementally increase the functionality that can be made available to Java ME, while also providing Carriers and OEMs the ability to prevent access, or limit access to provisioned software.
