I think most of members have f700/f900/f500. And there is a lot of topics for these units. i wanna know that, all modes and hacks doing for f700/f900 will also run for f500?

I have the 500 and all of my mods/hacks that I've used from this forum have been successful - so I'd say yes, they work on the 500 (unless relating to radio, which the 500 doesn't have).

thank you very much
