не только. строго говоря стандарта bluetooth 2.0 нет, есть Bluetooth 2.0 + EDR, EDR и есть та самая "скорость"
http://en.wikipedia.org/wiki/Bluetooth#Bluetooth_2.0The "Bluetooth 2.0 + EDR" specification given at the Bluetooth Special Interest Group (SIG) includes EDR and
there is no specification "Bluetooth 2.0" as used by many vendors. The HTC TyTN pocket PC phone, shows "Bluetooth 2.0 without EDR" on its data sheet.[8] In many cases it is not clear whether a product claiming to support "Bluetooth 2.0" actually supports the EDR higher transfer rate.
