Q: So I need a special bluetooth with my Iphone?  I have a samsung and it does not seem to connect.

The iPhone doesn't support that type of BT connection.  What are you trying to do?

The iPhone BT protocols do not connect to other phones ,iOS or otherwise

This is what you can do

When you say, "I am just trying to connect my bluetooth..." are you referring to a headset?

I am just trying to connect my bluetooth I already had for my other phone.

Connect for what reason?  Do you mean a bluetooth headset?

FYI, "Bluetooth" is a wireless connection technology, not a physical device, and is used to connect many devices.
