Programming for mobile but how testing

[k_mohsen]

Hi
I want to create some program for my mobile phone. (A custom converter, a custom calculator and some other)
But before installing I want to test it in simulator place.
My phone is E51, support .sis and java programs.
1.   How can I create my costume application? (C/C++ , Java , C# or other)
2.   How can I test them? I don’t want to lose my mobile phone.

Thanks

I searched and found all THIS -- none of which is a direct answer to your question.  Perhaps you can look at the types of software available, the companies which offer the software, and maybe contact some of the developers.
