Griffin Technology (http://www.griffintechnology.com) has unveiled their next generation of compact, multi-use docks. AirCurve Play (US$19.99) brings the acoustic simplicity of Griffin’s original AirCurve to the iPhone 4, and the $59.99 PowerDock Dual (pictured) allows simultaneous charging of and iPad and iPhone (or iPod).

AirCurve Play makes the speaker of your iPhone 4 10 decibels louder, and it works without batteries, cables, or power adapters. Just slip your iPhone into AirCurve’s rubber dock gasket, and your iPhone 4 becomes a portable audio/video conference phone, video viewer, and self-contained music player — even a beside alarm clock.

PowerDock Dual is a charging dock for iPad and iPhone and also a place for your stuff. The contents of your pockets — your keys, change, guitar picks — they all go in PowerDock Dual’s built-in valet dish, while your iPad and iPhone (or iPod) both get a seat of honor on the built-in charging docks.
