AT&T service in Chicago is not good. As I’ve noted on BccList.com and Twitter, the iPhone would would rule the cellphone world if it wasn’t for AT&T.
So, I don’t drive much. In fact, if I put 10 miles a month on our car, I would be shocked. I take either the train or bus nearly everywhere I can. The area I commonly need AT&T service is highlighted green. The areas that I have limited or no service in are highlighted red – including my walk home and our actual house. Thank goodness for wifi!
Less bars in more areas. Ouch!

I agree with you. Just signed up for it and the 3G is unusable for phone calls. I’ve switched it to the Edge network and it does work a lot better. This isn’t just a local issue either as there are a ton of complaints from Chicago residents about problems in the city.
Sean,
Good point – I didn’t even think about switching to Edge when I need to make a call.
Here’s an example around the Armitage brown line stop where there is absolutely no service. This is one of the most affluent areas in the city for gawd’s sake – come on AT&T!!!
