porting apps to blackberry.

Can you for free easily port your app (using the free version of unity) to blackberry?

 

The BlackBerry platform is included with the free version of Unity and can be selected from: File > Build Settings.

For Unity Pro license holders, the BlackBerry platform is included there at no additional cost as well.

For the most part, unless you are using platform-specific plugins, the building/packaging process should be more or less the same. Of course, different devices have different GPUs, CPUs, etc. so testing is recommended. If you build anything and would like to have it tested before submitting to the storefront, feel free to reach out to me directly.

You do need to request/register code signing keys, which are also free. These keys are used to identify you as the author of the applications you produce. The best place to get more information would be the Getting Started guide:
http://docs.unity3d.com/Manual/bb10-gettingstarted.html

Submitting to BlackBerry World is free, as is registering to become a developer. The revenue split is the standard 70:30, in favour of the developer.

Don't hesitate to reach out if you have any additional questions.

 

does it work the same way for every platform?

 

For the most part, yes the process is the same. Each platform may have its own variation on code signing and storefront submission (some platforms have fees, etc.), but in terms of the development and packaging steps, Unity does a great job of keeping the process, well, unified while still allowing you to customize for specific platforms where needed.
