My cellphone has been flakey lately. I'm having all sorts of issues with service, and spots that didn't used to be drop-out zones suddenly are. It's partly the phone dying, but the Wall Street Journal reports that some cellular companies are letting their networks degrade in order to push customers to newer systems. If there are spots you know always kill your calls, submit them to the DeadCellZones.com database, which tracks bad spots in Chicago and other cities.
