Thanks for the update! We've had issues with Clear in other cities.
FYI - I work in the telecommunications industry, and recently (May 2011) got information from Sprint engineers that leads me to believe that Clear's days are numbered. There are some upcoming changes in the Sprint's cellular frequency usage that may require them to reclaim the parts of the radio spectrum being used by Clear's WiMax service for other purposes. Probably beginning late 2011 or 2012. I wouldn't bank on Clear (besides, it was really awful in the Texas area anyway).
