If you're like me and spend 50% or more of your life reading the Sky Mall and United Airlines magazines in the seat back pocket in front of you, and if you also happen to have a Blackberry with a web browser enabled, or some other SmartPhone-ish thing that lets you browse the web, be sure to check out United 2 Go:

http://www.ua2go.com

Among the things you can do or check on this mobile-enabled site:

• My itineraries: View your United Airlines and United Express segments regardless of where they were booked.
• Flight availability: View domestic and international flight availability up to 331 days in the future on United flights. For Palm OS device's without a wireless connection, the downloadable electronic timetable is available monthly on united.com.
• Flight status: This gives you up to the minute flight status that includes departure/arrival times, gate numbers and departure/arrival status for United flights.
• Flight paging: Much like the Flight status alerts feature on united.com this allows you to request flight paging for future United flights
