Well, here's an update. I started looking for a schematic to do the cable. I found this one
. It isn't for the Fisio 316, but for the Savvy, Az@lis and Ozeo. I took a look at the Philips website, and Ozeo uses the same data cable as the Fisio 316, so I imagine it can be used succesfully in my phone.
Is that right? Do you know anywhere I can find a specific schematic for the Fisio 316?
