I saw a program which turns your ppc to a usb memory (the internal memory and the card) when connecting to a desktop - not with the usual way of sincronization by activesinc but like a usb stick, neutralizing the activesinc.
It didn't work - but I like the idea.
I tried it again - still the desktop doesn't like the idea.
It is a dangerous program - my ppc now has an activesync problem and i'll have to reset it.
