I have a Iphone 3gs and a Nexus 7 tablet. When I first bought the Nexus 7, I had Jellybean 4.1 on it and I was able to get on the internet by tethering my phone to the tablet. I would pair them up via bluetooth and then put my phone on as a hotspot. It worked fine until I updated my Jellybean to 4.2 and now it doesn't connect. Could someone let me know how this could be fixed or if they had the same problem.
