Anyone else having problems with the Cingular data network being down for the past few days? I called into customer service and they said it was down due to maint of towers. I've been out of service for a few days and it seems this would be limited to my area (Seattle) and they confirmed a national problem, so I don't really believe the answer...especially since they said they can't give any advance notice (this is really appalling if true for a multi-day outage). I really wonder if they have major network problems.
