...particularly in SF and East Bay. For background, I have a J/B 3GS 3.1.2. I haven't installed any new apps for the last month. Over the last couple of weeks, my reception starts out great in the morning (around 5:30), but by about Noon my reception drops significantly. By about 3 PM, I have virtually no reception and people trying to call me can't connect. When calls do connect, the call quality is terrible and I end up calling them back from my office phone. This is all in my office, mind you, I'm not moving around. While in Berkeley, where I used to get great reception up until last week, I've actually been getting the roaming icon . Anyhow, I was wondering if anyone else has been experiencing this in the Nor Cal Bay Area. Any thoughts on why this is happening, could it be the phone itself?
