First i should note that this is my second iPhone and that the my first one was replaced due to the exact issues I am experiencing now. I will probably end up getting #2 replaced for the same reason. Also I was wondering if it is true that if your serial number starts with a "5K" then your iPhone is a refurb. My only crime is that I let the battery die. I plug it in and get this. It never activates though because it is not getting a signal. It alternates between 1 bar and no bars (I always thought Apple/AT&T overestimated the signal) but it never connects to anything unless I use WiFi. So now my iPhone is USELESS as a phone. So I do a restore. Now things get weird: there is an unavoidable lag when doing anything on the iPhone as if it's got something else on it's mind or it's getting stuck. Like if I'm entering my passcode it gets stuck on the first digit for about 10 seconds and then awknowledges the rest of my input and takes me to the home screen. Then after exactly 4 minutes later it restarts itself. And the restarting cycles does not stop. Not even after Recovery Mode. My last iPhone seemed to get smart when I got to the Genius Bar; it proclaimed that there was a problem with the cellular reception or something (I don't have that screenshot... yet). A Genius Bar trip is in my near future and I will let ya'll know if I find anything else out or get any new screenies. BTW, not jailbroken, unlocked, bounced off the ceiling, used as a frisbee or any other warranty-voiding activity.
