iFusion from Altigen
The iFusion dock will accept the iPhone 3G, 3GS and 4, and provides power, battery charging and data synchronization via an integrated USB cable. There’s both a handset and a hands-free speakerphone, and the five buttons on the phone control Bluetooth pairing, mute, speakerphone, volume up and volume down. A 3.5mm stereo port allows you to attach external speakers.
The iFusion is available in black or white, has a retail price of US$169, and will be shipping in April 2011. Pre-orders can be made now, and will enjoy a $20 discount.
