With which applications can music, photos, videos or contacts be transferred from the iPhone?

iDevices are truly extraordinary gadgets, but they naturally lack a basic functionality: the ability to transfer files between them or with other terminals via BlueTooth or Wi-Fi. Apple has limited/blocked in iOS the possibility of sending any type of files via BlueTooth, but has accepted in the AppStore applications that implement this functionality. I have been asked countless times about methods by which any type of file can be transferred from one iPhone to another iPhone or another terminal, so here are some applications (found with a simple search in the AppStore) that will help you transfer: photos, music, videos and contacts via Wi-Fi, BlueTooth or 3G from any iDevice.

LoKast - free, allows transfer of music, photos, videos and contacts via Wi-Fi, BlueTooth and 3G.
