Time Warner to Relieve Verizon & AT&T's Data Congestion? Could It Speed Up Your BlackBerry?

Bloomberg's Business Week is reporting that Time Warner Cable is pitching an idea to the large cellular companies (AT&T/Verizon) to help ease the congestion that Blackberry's and iPhone's create.  As most of us are aware, AT&T's network is under a lot of strain due to the massive number of 3G iPhone users, and Blackberry users do contribute also.  What Time Warner is pitching to these companies is to route some of the wireless data through their pre-existing underground cables which would help to decongest AT&T and Verizon's existing strained networks.  Personally I don't think it's a bad idea, if these wireless companies aren't willing to spend the money and upgrade their networks to where they need to be, then I'm all for Time Warner trying to get their piece of the pie.  What do you think?
