: Interaction of cell phone and PDA. Navigation throws files? Remote Control?

[Proteus]

I have a Nokia 6230 (which has java and Bluetooth) and x50v (WM5).
Since I buy my axim, about one year ago, I have learned a lot of thinks. Thanks to aximsite.com!
But some answers I not have found here or anywhere. There we go…

1)What program I use for remote control my PDA through my cell phone? Maybe control a PowerPoint presentation or windows media player.

2)How I can see and navigating in files on my cell phone through my PDA?
And the inverse, can I navigate in files on PDA through my cell phone?

Thanks for the help.
