There is an application called iBluetooth that was the first iPhone application to send / receive files over the bluetooth to other devices (for jail broken iphone and ipod’s) but with limitation, that this wonderful app supported only the iphone 2.0 firmware.
Now the same team is going to launch the iPhone app iBlueNova to be used by the jailbroken iPhone and iPod touch running the iPhone 3.0 firmware for transferring files over bluetooth.
The application iBlueNova is currently in beta testing stage and has already been released to some private beta testers and the final version will be released out soon.
iBlueNova will use its own file manager to manage your files on the iPhone and will also be supporting the iFile app.
