I am looking for reviews from people who own speaker docks for their iPhone 3gs. I would ideally prefer a dock that will work with the 1st gen iPhone as well, since we have a couple of those in the household. What do you like, and why? We have an iPod doc (Altec Lansing) that I bought for my bf for Christmas. It works reasonably well, but there's that feedback thing when the phone rings in the dock (which is rare, but again, annoying). Anyone have a good recommendation?
