Update: T-Mobile acknowledged some trouble via Twitter and has since taken to Twitter again and pronounced the trouble over!

There are a large number of reports coming into our inbox and @TmoNews Twitter regarding a possible outage in Chicago. We managed to grab a screen shot from a Chicago area store letting us know that Chicago is suffering from an inability to make/receive calls. We’ve pinged T-Mobile to see if we can get an update and we’ll update as soon as we know whats up!
