I remember waiting for what seemed like an eternity to purchase a Linux based cell phone. I was stuck on T-Mobile's network with the T-Mobile Wing which, for it's time, was a decent Window's based cell phone.
When the G1, the first Android based cell phone hit the market, I was one of the first to pre-order the phone. Not only did it have a keyboard, but it was Linux based and built upon an open source operating system called Android.
Two years later, it seems T-Mobile is planning a G1 blaze, rumored to be the HTC Vision. It's also rumored to have a 3.7 inch screen and a 1 GHZ processor, as well as a keyboard.
I was going to upgrade my phone tomorrow for the MyTouch Slide, or even the Samsung Vibrant, but I will be waiting for this phone, supposedly due out September 9th, a very special date for me anyway.
