These are the supported Bluetooth profiles: http://support.apple.com/kb/HT3647
There is no support for Bluetooth connections to PCs or phones except for Internet Tethering (Personal Hotspot via PAN on iPhone) or for using third-party apps that provide peer-to-peer Bluetooth connectivity between iOS devices running the same app (such as photo sharing apps, e.g., Photo Transfer, multi-player games, etc).
What are you trying to do between these 2 devices over Bluetooth?
