My T-Mobile G1 is my preferred T-Mobile device and it just gets better and better all the time with more developers supporting the Google Android platform. The latest software/service available for the Android devices is Qik mobile video streaming application. iPhone users cannot say, "There's an app for that." since Apple still does not allow video streaming with Qik. I have been using Qik a bit lately on my Nokia N97 because it allows me to simultaneously upload videos I take to Facebook and YouTube, as well as my Qik site. The Qik Android alpha requires a device with firmware 1.5 (aka Cupcake) and a microSD card.
