For years I have been using my phone in my house and never had a problem with reception. Over the past few months the signal has dropped to one bar. I can't make calls from my basement anymore. I don't know what changed. I am using an iPhone 4 in the 19438 area. Has anyone experienced a similar drop in 3G signal strength? I did a speed test and the ping took 280ms and the download speed was 0.63Mbps.
