I would like to make my own applications for my 5800 but I don't know where to start... I've been programming windows applications in C# and VB for like 4-5 years but since none of these are working on the 5800, I thought of learning Java ME.

So, do you mobile developers out there recommend Java ME for development on the 5800? If you don't, what program do you recommend?

Thanks in advance!
