3.0 is the fastest, allowing for data transfer. Basically, it has the potential for wireless Blu-Ray players, etc.
2.1 is basically a very short-distance radio wave (id say 50 feet-ish), but with far less power consumption, ability to identify objects by name, and change passwords
3.0 having far greater rates than its predecessors. And the frequencies are different.
So Fast...Thanks Priyanka

Bluetooth 3.0 Features Launched in July, 2009, the Bluetooth v3.0 + HS (High Speed) was
aimed at increasing the throughput of data exchanged over a
Bluetooth connection. With the combination of a 802.11 link, Bluetooth
3.0 devices can provide a maximum data transfer rate of 24 Mbps.
While initial connection is made using Bluetooth frequencies, a MAC
PHY 802.11 link established between devices handles the rest of the heavy data transport, enabling higher overall transmission speeds. MAC
stands for 'Media Access Control' and PHY stands for the 'Physical Link
Layer' of the OSI model, which describes any network. Through version 3.0, a further reduction in the power consumption of
Bluetooth devices has been achieved. Through this version, the
Bluetooth protocol has been applied over 802.11 frequencies, used by
Wi-Fi connections, to achieve higher data throughput. To summarize,
Bluetooth 3.0 essentially piggybacks on Wi-Fi frequencies to make this
