The N810 will not back up using PC Suite because, as the error message states: the N810 is not a phone. PC Suite is designed to sync a PC with a Symbian OS phone. The Internet tablet does not run on the Symbian OS. I don't know of an app to backup your IT to a PC directly but I wonder whether an indirect method might work, which would be backup to one of your SD cards and then transfer the contents from the SD card to your PC and reverse the process to restore. I haven't tried this, just a suggestion if you want to try it and let others know how or if it worked.
Will the N810 work with pc suite? Pc suite says "incompatible phone"..?
