AT&T has network problems?

On the same day that Apple's touchscreen delight can be bought at a Wal-Mart or Sam's Club near you, the gerbils stop spinning the wheel and Ma Bell's network drops out. According to readers of BoyGeniusReport and Engadget, customers are having problems with the AT&T network in different parts of the country. Some have problems connecting to 3G or using the BlackBerry service, but some report that they cannot make a single phone call. BGR says that AT&T has confirmed there are network troubles, but without specifying which regions are affected.

Do you have problems with AT&T or you are blessed to be in an area with good signal? Please, tell us in the comments.
