So, i downloaded their doc. iirc, they had three ways to develop apps. one was using web technology, and you couldn't do much. then they had two different sets of java apis : an old, discontinued one, with which you seemed to be able to have things work, and a new one, soon to be released, and undocumented.
so i installed their sdk, on my mac, and tried to run a "hello world". but their sdk required windows, because the simulator didn't exist on mac. i had just bought and dual-boot installed a windows 7. but the sdk was just for xp, so i had to run an XP vm inside my windows. then i launched eclipse, to launch the simulator, to launch the Java program that was supposed to run my hello world.
i never was patient enough for that hello world to show.
then i said " well...let's get back to that once a customer ask for a blackberry development".
and guess what, that customer never came.
