On the more general topic of whitepages.com: The thing that frustrates me about whitepages and similar sites is they don't allow me to build up my own phonebook. Say I want to look up the number of a restaurant - after I have done that once, I want to add it to a virtual address book, maybe even something I can sync with my mobile phone (eg. via Google contacts or something else that nuevasync supports). Does anyone here know of a site allowing that? I know, I know, I have asked this before...
