Hi all, I just ordered a Nexus 7. I would like to tether it to my phone for internet. Preferably for free. I see in research people talk about Wifi Tether and FoxFi. There is also a Bluetooth option I have read about. The complaint is the upgrade from 4.1.2 to 4.2 caused the Bluetooth method to fail with no fix. Claims said it still works with 4.1.2. The problems seemed to be related to cross versioning of the phone and tablet. My question is. What will work with my combination?
