iPhone 5 tether issues
I recently purchased an iPhone 5 with carrier AT&T. My tether feature was working intermittently, and now doesn't work at all. AT&T says it is the apple software on the phone. Apple says it is ATT. I replaced the phone after all the troubleshooting from both companies. Still doesn't work! HELP! Anybody out there having the same problem?
