I’m really digging the look of this iPhone Horn Stand. The Horn Stand acoustically amplifies the volume coming from your phone by more than double without any wires, batteries or power (just the power of simple physics!) Made of super tough silicone, the iPhone Horn Stand can be used either horizontally or vertically:
A slot in the bottom allows you complete access to your phone’s dock connector. The iPhone Horn Stand is designed for the iPhone 4 but is also compatible with the iPhone 3G/3GS. Comes in green or black for $24.95 from Vat19.
