It is an SDK for the iPhone! :P Anyway, it is NOT open sourced and deploying
apps require that you sign-up (and get approved) by Apple for inclusion in
their AppStore. Whilst this has vast potential considering the hype, open
source development is very difficult.

Technologies such as JIT compilers make Java as fast as C/C++ in some
aspects. On the Mobile, you have JavaME as the largest SDK available in the
market today. PhoneMe is its open source base, similar to OpenSolaris and
Solaris 10.

BTW, have you tried the games bundled with Sony Ericsson mobile phones - 3D
tennis, etc.? Tell me if it is slow - oh, it is a Java midlet. :P

You left out Android, which runs on open source technologies - Linux and a
Java-like development environment.
