Roll Your Own Software

Having downloaded every application, plugin and theme for your phone under the sun, you may be thinking about writing your own stuff. Here are some hints and tips for you:

Do you want to write a today plugin? You will have to do this in C++, you can't do it in VB.NET or C# (edit: Well, OK, so you can use a combination of C++ and C#, but to get it, you'll need the code and walkthrough from here).

Looking for some forums with good information about software development? Try the forums at xda-developers.com - specifically the Hacking and Development forum (where you'll also find an interesting post about one software author's tools).
