In my house, I have a pretty weak signal, usually hovering between 2 or 3 bars. What this does is cause the iPhone to work hard at keeping a signal, which in turn drains the batteries of both me and my wife's iPhones. We addressed this by getting the ATT Microcell, which has worked great. I have been able to toggle airplane mode and get it to kick on, but only for a time, then it appears to jump off when it gets a little better signal, which is still subpar. I think I'm stuck on this and forced to keep using the mcell but thought I would see if anyone had any solutions for this.
