The iBamboo Speaker ($TBA) is sure to become one of your favorite audio dock for your iPhone 4. The iBamboo’s unibody (see what we did there?) is fashioned from a single bamboo to amplify the sound produced by the device’s built-in speaker. And since the iBamboo is designed to move sound in two directions at once, you’ll also get a cool stereo effect from your dinky iPhone speaker.
