Bluetooth file transfer in iPhone?

How to transfer files from iPhone to Non-iPhone using Bluetooth and without jail-breaking the iPhone? Are there any apps to do so? Why is Apple not allowing this basic feature?

When you say "file transfer" do you mean music files? Apple doesn't allow accessing the music files and sending them in any way. I believe this is due to legal issues - they don't want you to send copyright material to other people for free. For other files, there are apps for that. You can use Mover+. However, this is only iOS device to iOS device, you can't send to other devices. I would recommend just getting Whatsapp and sending it as a free I'm.
