Bluetooth EDR (enhanced data rate) alters the signal encoding system used by Bluetooth to allow it to transmit at up to 3 megabits per second, several times faster than the third of a megabit or so of conventional Bluetooth 1.1 devices, while while reducing power consumption and still maintaining backward compatibility with older products (at slower data speeds).
While short data bursts really can't get much faster, that does open up the possibility for streaming audio over Bluetooth from a phone to a headset, using a 3G-capable phone as a wireless modem for a laptop, and other high-bandwidth features.
