It appears there is a network issue on AT&T in Kentucky and Tennessee. I just placed a call to customer support and this started a little after 10 am, but I didn't notice it till I got up this afternoon. I can not get any e-mails or even use the internet on my curve 8310 and they are not sure how long it will last.

apparently some issues in DC too, voice coverage is nonexistent and BlackBerry service is spotty at best.

i am able to use my phone to make calls and send text messages but thats it.
