Useful links for people who are knowledgeable in programming, but is currently new to programming for the BlackBerry or cellphone programming in general.
There are two main methods: (A) Run on Just BlackBerry:
The advantages is that you have a much more comprehensive API, with an easier development environment that already has the BlackBerry Emulator integrated into it. You just need to download the RIM JDE, install it, and compile away. The 4.x environment is completely integrated and even comes with a free "Hello World" type samples that you can compile, run, or install on your BlackBerry right away. Alternatively: (B) Run on Multiple Cellphones:
Did you know you can write a generic Java midlet that works on multiple cellphones? Yes, including BlackBerry, Nokia, Motorola, SonyEricsson, etc. Examples of phone-independent Java midlet software that runs on BlackBerry too
. If you need to cast a wide net because you think the Blackberry market is too small despite over one million users, this is an option you can go to gain a bigger potential market to justify development. Alternatively, you can benefit with using BlackBerry extensions for a BlackBerry-specific application! In fact, you can write for both, and automatically use the BlackBerry extensions if you're running on a BlackBerry, too!
The optional $100 code signing key simply permit more flexible development such as programmatically modifying PIM, bluetooth programming, programatically dialing numbers, loading/saving settings, etc. The key is unlimited use; you can use this key as often as you want for as many applications you want, released under your name or your company name.
