I have an iPhone and I have thought of using my mobile internet connection with my laptop by connecting it using tethering, but I am unable to connect it. There are two options to connect it USB and Bluetooth and I have tried both ways but been unsuccessful. Does the tethering actually work with iPhone as I have never heard anyone use tethering with the iPhone.
Not many people who tethering on their iPhone which is why its not an issue which is generally raised or known about, but the same problem was with my iPhone too. After such problems I switched to the Samsung phones which are much better. I never actually got the matter looked into either, so its a good try to have someone look into it.
