AT&T boosting EDGE speed ahead of iPhone?

Numerous reports from across the country are indicating that EDGE speeds over AT&T’s network have seen a dramatic increase over the last twelve hours or so. Many are convinced that this sudden boost in speed — some are seeing results well over 200Kbps — is connected to the iPhone launch. It was previously rumored that such an upgrade was coming, but marked speed improvements had not been noticeable until now.
