So I was rolling down the road today and noticed my phone light up. It showed "NO SIM INSTALLED." Of course, I freaked out thinking that AT&T had figured out I had a hacked phone and cut me off. Fortunately, I removed the SIM when I got home, waited a couple seconds to put it back in, and then it regained service. Nevertheless, it is a bit concerning. Has this happened to anyone else? Phone is hacked (unlocked and jailbroken) with 1.0.2 firmware.
