I finally received the 5.9.905 update.  I am still frequently being disconnected from 4g.  If I switch to 3g, then it is completely stable...I just cannot stand the 3g speed after zipping along on 4g.

Other than this small group, I don't see complaints reported any where else.  Is it just Bionic owners with this problem?  Just users in a certain area/region?  If anyone else is experiencing 4g disconnects, please state your device and market.  I've had this behavior for a week!
