I'm planning for mobile software development as a hobby over this holiday festive period and i would like to know whether mobile apps developed using JavaME works on my mobile device.

Mobile: Blackberry Curve 8520 (model kinda old, about nearly 2 years now)
Mobile Software: Most up-to-date version (4.3. ...)
Programming Language: Java via the use of JavaME

thanks in advance
