The worst time to find out about gridlock is when you're in it. With MapQuest Traffic (www.mapquest.com/mobile), you get access to live traffic updates on your Verizon mobile phone (more carriers plan to offer the service soon), zoomable maps of backups and accidents, and an optional text message if there's trouble on your morning route. The $3 monthly fee includes information for 85-plus metro areas, so your cell can keep you moving while you're roaming — the roads, that is.
