I cannot pair the iPhone 4 with the iPad Mini. Both Bluetooth are on but they cannot see each other for pairing.
That's because they are not supposed to pair. You can't transfer files using Bluetooth on iDevices. It's not supported.
You need to turn on both Personal Hotspot (on iPhone) and Bluetooth, then iPhone and iPad mini can see each other and pair.
If you want to pair it to transfer photos, you need 3rd part apps.
