I need help to setup Bluetooth in my iPhone.

Which other Bluetooth devices specifically?

The iPhone works with Bluetooth headsets, headphones, speakers, car systems, internet tethering and some iOS apps with Bluetooth functionaility.

If you are trying to use Bluetooth for any other function, with any other device, it won't work.
