Hi, Apologies if this has been addressed, I tried a few different search strings and I couldn't find any posts about this. Ever since I got my iPhone 4, I've run into this issue twice: The phone will display no bars and no matter where I am I can't get reception. The phone does not receive calls or texts. Both times this happened it was at my house. Depending on where I am in my house I get from about 2 to 4 bars. Basically, if I have low reception I can normally move around and find a decent reception area - not so when this issue happens. If I reboot the phone, this fixes the issue. But seeing as this has happened twice, the "fix" isn't quite permanent. Today was the second time the issue happened, so I rebooted the phone and then I also did a settings reset. We'll see if that fixes it. (edit) This has happened running both iOS 4.0 and 4.0.1. I am not holding the phone when this starts to happen. (edit 2) My carrier is AT&T. Has anyone else had this issue? Has a fix been found that keeps this issue from popping up again? Cliff notes: 1) Phone loses cellular reception "permenantly"; can't receive texts or calls. 2) Only way to "fix" is to reboot the phone. 3) Want to know if anyone has found a solution that fixes this issue permanently. Thanks, Andrew UPDATE: I got a new SIM card from AT&T. It's been a month since I've ran into the issue so I'm confident that this has been resolved.
