I have a weird problem. My iPhone 3GS, and my wife's iPhone 3G, works beautifully everywhere except our home. We even took them camping with us over the weekend and we got reception way up in the mountains. Now, my bars are full. I did a field test and its rendering at about -95. But I cannot send texts, I receive texts twenty to thirty minutes after they are sent, and I cannot make calls. I can sometimes receive them, but when i answer the person on the other line cannot hear me. Once again I have FULL BARS. The only place the phone works great in my house is in the bathroom close to the toilet. And I'm not joking haha. I have never really had any problems before the last few weeks in my home. I live in Louisville, KY, a fairly big city with plenty of towers around. I went to AT&T they sent me an update via phone, didn't work. Gave me a new SIM CARD didn't work. I have don't a factory restore on the phone and a hard reset; didn't work. I have an appointment with the Genius Bar tomorrow night, but I was just wondering if anyone had any similar problems or solutions. Do you guys think this is an Apple Problem, or an AT&T?? The Full Bars yet still not making calls seems an iPhone issue maybe, but I don't know. Any help would be appreciated.
