"There is no emulator

There's no emulator available. I suppose it's no shock that the nokia emulator for windows doesn't run on Mac OS X. In fact, it doesn't run on wine either [edit:I believe it does if you use the opl version and not the java sdk version]. Is that really such a bad thing? It depends. The "emulator" is actually NOT an emulator, it's a simulator. It doesn't actually emulate the ARM instruction set. Instead, they have effectively ported the entire Symbian / Series 60 API to windows. You build a windows binary file, which links against the ported libraries. "

I think the simulator in the opoc sdk is opoc.exe

Sooo...

*COUGH*
