I'd give up a 2nd if im a team needing wr help. Miami should be all over this. At a glance, it's a great fit. The Dolphins have 2 2nd round picks, Harvin's still on his rookie deal, and the Dolphins need a receiver, particularly one who is a threat downfield. It gets more complicated with deeper exploration. Harvin is more of a slot receiver. The Dolphins have Davone Bess, who is a pretty quality slot guy, already. Their greatest need is on the perimeter. At this very moment in time, their 1 and 2 perimeter receivers are Marlon Moore and Rishard Matthews. (Hartline is a free agent.) Harvin doesn't really help with that, and while Harvin is an improvement over anything on the roster, you would still be adding to a strength. Assuming they resign Hartline and trade for Harvin, they still lack a dependable perimeter threat and now have a pretty small receiving corps overall. It's not a move I would frown on, but it's definitely not an all-encompassing solution to their needs.
