If somebody can help me if he/she knows…

If I have a Gmail account with a thousand contacts and each of the contacts have multiple “informations” and phone numbers like, 4 mobiles, 2 general phones, 2 home phones, 2 business mobiles, 2 fax, 6 e-mails and 2 notes, I want to ask you that. What’s the Nokia phone that I can synchronize that mail, to have always my contacts (and calendar I think) synchronized all the time, in order not to transfer my contacts from one to another and to have always a back up! Androids can do that for sure! I think Symbians also, but I’m not sure. Can N9 do this?? I think that Lumia can’t! They told me when I called Nokia calling center that Lumia has only two “seats” for mobiles in each contact and N9 3, but I don’t trust them because they had told me wrong informations before about sth else. They have not been adviced such good. I want to know espesially for N9 or another…

Also if (qwazix) sb knows, if I have a N9 and put the greek keyboard, can I write in capital letters only or in small too?? Will it have tones on the small letters??
Thanks!
