The crippling of Bluetooth functionality on the iPhone is another one of life's mysteries. As users are painfully aware, the only thing Bluetooth is capable of doing in firmware 2.2 is connecting to a wireless headset. Fortunately for those with jailbroken devices it appears that all of this is about to change.
The iSpazio Repository will soon host software from the iBluetooth project allowing users to unlock Bluetooth on the iPhone and transfer files using a computer or another Bluetooth-enabled phone. This is only the tip of the iceberg. The Bluesn0w project promises to allow developers full access to Bluetooth on the iPhone.
