Apologies for coming across as rude and offending.

When you pair a device, there's a checkbox "Set as trusted device".. If you leave that ticked the device has full access. When you leave it unticked, the N900 asks you each time the device wants to connect, and then if you accept that device will have full access to MyDocs again..

Set as trusted is something I'd only use for my own devices, no for anybody else's devices..
