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.
Already released is the application SweetTooth, available using the Cydia package manager. At this stage the application simply scans for Bluetooth devices in proximity to the iPhone. Still, a great start to developing long overdue functionality.
Future software should make it possible to pair the iPhone with other devices, use A2DP speakers, make the iPhone discoverable, or use Bluetooth peripherals such as wireless keyboards or mice. Just think of the possibilities. Hopefully it won't be long before the iPhone user can enjoy the phone's Bluetooth capabilities to the fullest extent possible.
