With Desk Phone Dock you can use your iPhone as an integrated device with your land line. You are able to use your iPhone address book, so you never have to look up a number again. Of course it charges your iPhone and it is equipped with two stereo speakers and an inbuilt microphone.
According to engadget.com the Desk Phone Dock will make its debut at the China Sourcing Fair next month. Prices are not available at this time. And it is not clear when it will be available for (pre) order.
Well again, I am not sure about this device. It looks cool and it certainly saves you a desk phone.
