Z-Com, a chain of wireless stores, is debuting a marketing campaign based on the BlackBerry faux pas that may have insulted billionaire Tom Golisano enough to stage a coup in Albany.

Class dismissed.”) are being offered at over 100 stores, and newspaper ads will tell customers to “Ask Malcolm” about the power of the BlackBerry a reference we’re sure dozens of people will appreciate.
