Actually, I don't know Linux at all but, worse yet, I don't do anything on the N8x0's in the areas you are asking. For mail, I prefer to stay web-based rather than use a client. For chat client with the webcam, I'm pretty sure you're just out-of-luck with using the webcam with those chat clients. see, e.g., http://talk.maemo.org/showthread.php?t=14529 but with http://talk.maemo.org/showthread.php?t=15463 and http://talk.maemo.org/showthread.php...631#post268631 I don't know anything about your specific phones, nor have I tethered my N800, but there's no help in any of these threads?
