Using BlackBerryOS 4.0 here;
BlackBerryOS 4.0 has a subset of MIDP 2.0 (part of it) -- including videogame API's. The enhancements are obvious in the BrickBreaker software, and I downloaded the test software on my BlackBerry from http://mobu.com/wap
... and the Download test worked for my BlackBerry with a crude 3D vector graphics demo that seemed to run at about 15-20 frames per second. Running on my 7280.
I am tempted to purchase a few videogames from www.mobu.com
and "masquerade" as a certain Nokia/Motorola phone
or some other java capable phone with 240x160 screen, to see if I can get any of those games working on my BlackBerry:
I know 240x160 midlets run in the center of the BlackBerry screen. If anyone wants to "waste" 4.99 euros on testing some videogames under BlackBerryOS 4.0 (preferably build 18.104.22.168), please feel free to do so and let me know what your results are.
I am 80% sure that at least some of the games will work; some of them are just generic MIDP 2.0 midlets that only use the gaming API's. Of course, websites such as mobu will no doubt include support for 7100v very soon later this year.
There is indeed, a much better videogaming API available in BlackBerryOS 4.0 as it seems that some nice fancy graphics demos actually work.
