T-Mobile's data services (GPRS/EDGE) have been out in the Minneapolis area since around 8:00 CST this morning. I just got off the phone with T-Mobile support and they verified that they are still having data service issues. At this point, there is no ETR. The master ticket # for this incident is 541847.
