I have acquired an iPhone 3GS in order to be able to occasionally tether with my iPad mini (wi-fi). The Apple website said I could do this over Bluetooth. I tried it on a train a few days after getting the phone and it worked very well, just as fast as when I have used other phones with wi-fi tethering.
But then the next time I tried it wouldn't even connect/pair with the iPad and it hasn't done since, the iPad can't even detect it. I did once completely restore the phone and I noticed that it did detect the iPad for about 3 or 4 seconds then it lost it.
The iPhone has IOS 6.1.3 and the iPad Mini has IOS 7
Any thoughts?
