I still have my old 2G iphone and the dock. I had the dock sitting on the table and i just put my new iphone 4G on it and it fits perfectly!! Charges and everything. So those of you that still have one, use it
Sweet, I do still have one for whatever reason, and *almost* gave it away when I sold a bunch of old broken 2G's... glad I was lazy and left it in that storage box instead!
