Transfering files between iPhone, iPod and iPad using bluetooth functionality is probably one of the most important things that’s missing on the iDevice. However, a third-party apps developer has now come up with an app called Celeste that can do all this with ease.
Celeste also allows file transfer to other devices that are bluetooth ready. It supports various types of files including MP3, photos and contacts etc.
This wonderful app is available for $9.99 via the ModMyi repo (it requires iOS 4.2 and above). That means your device needs to be jailbroken first before you can install it.
