Protip: T-mobile has one of the more reasonable data policies. If you're somewhere with no WiFi, you just plug your phone (in my case, a MyTouch 4G) into your laptop and set it to tethering mode. After hitting your cap (200MB, 1GB, or 2GB), your connection slows down but is still quite usable. No overage charges, no kill switch (but alas, slow video). Likewise, when you are somewhere with WiFi but no cell phone signal, T-mobile will seamlessly route your calls over your phone's WiFi connection. I bring this up because people still mention WiFi (in the article in regards to a cafe, and now here in regards to transit) as if it really matters anymore. For $60 a month, you can get 200 Anytime minutes, unlimited messaging, unlimited data, and connectivity everywhere that you have cell phone service; $10 more gives you unlimited calling, too. Oh, and they have great, patient, helpful customer service. I don't work for them or benefit from this post in any way, I'm just a very satisfied customer.
