Q: Can you connect to non apple devices with bluetooth?

What exactly are you trying to do?

You cannot pair an iPhone to another phone.

READ the article from which the question was posted, it explictly details the supported bluetooth profiles and what is possible.

Bluetooth is supported for stereo speakers/headsets, handsfree telephone devices, some keyboards, some apps from the app store, and internet tethering (if provided by the carrier).

Otherwise, it will not connect to a phone/computer/ipad/ipod/etc
