Title's question is about smartphone but you asked about first mobile phone.
So just in case. I don't remember much but my first mobile phone is probably 1995 and Samsung, I think.
And then smartphone is hard question for me because Nokia N8 is smartphone but not many people think Nokia Symbian phone as smartphone. But I can call it that--Nokia 6210s and it was 2009.
The first phone was bought in 2001 and this phone was the legendary Nokia 3310 :) and the first smartphone was Nokia E51 in 2007. I had navigation maps, music, organizer, some games and even Skype there.
