Apple Thoughts: AT&T MicroCell in San Francisco

"If AT&T gets a bad wrap for having poor signal quality in any city, it's San Francisco. Part of this is due to the sudden influx of iPhones in the Silicon Valley that began in 2007, putting an almighty strain on the network; of the roughly 800,000 or so people living in San Francisco, we're estimating that around 10 million of them (or 1,150%) are carrying iPhones. Throw in ridiculous topography and monstrous buildings, and it starts to get tough to properly blanket the entire area in radio waves."

It should get a little easier since this past weekend AT&T started selling their 3G MicroCell in the San Francisco area.
