The emulator runs in a browser on your phone.
If you have a modern, non text-only, browser you should be able to run it.

(Applications on this website were built for a Nokia 5230 phone because that is what I have and what gave me the original idea.

These phones have the same operating system and screen size:
Nokia: 5230, 5233, 5235, 5250, 5530, 5800, C5-03, C6-00, N97, X6
Samsung: i8910
Sony Ericsson: Satio, Vivaz

It's only fair to share...
