I restarted my phone and when it came back on, it said No SIM all of the sudden. The SIM was definitely still in there. I restarted the phone over and over and it still said No SIM. Then I took the SIM out and put it back in perfectly, still No SIM. So basically on iDay 2 the rest of the day my phone was out of commission. It wasn't until later that night when I restored my phone that it fixed the problem. VERY weird. I talked to my friend and he said that he has gotten that No SIM error on and off ever since he got it. This happened on day 1, I hope it doesn't ever happen again, especially when I'm stuck on the side of the road with no computer to restore my phone in.
