LoL...do you think I'll be here if I do HAVE THE solution? My point is, why hasn't Nokia try to come up with something? IMO, sync by sending delta and combined checksum is a viable solution (how do you think e-mails get sync?). About your installing porn...You give your (almost) entire asset to a bank or banks...and you worry about porn? Even your personal e-mails are hosted elsewhere (maybe not you, maybe you have your own mail servers)...hum.
