From a reader:
Just so you know, the version of EVDO you are using is about to be upgraded. The new name of the product will be EVDO Revision A. Verizon and Sprint both offer EVDO service and are gearing up for Revision A service next year. It will potentially be twice as fast as what you have now. A Revision B is now in beta testing and it may be available in two or three years. Revision B will have speeds that will rival cable broadband speeds. Thought you would like to know.
