Samsung Vibrant is a mobile phone also known as T959 Galaxy S and this is not just some coincidence. This phone is built on the same platform as I9000 Galaxy S and has 99% the same features. With other words, this is the T-mobile version of the I9000 Galaxy S. A few differences that can be named are the design, the processor which is only of another brand, but with the same 1Ghz frequency and the mass storage memory which is 16Gb with 2Gb microSD card included. In rest, you can enjoy the same extra large 4" Super Amoled display with all the known related features, the Wi-Fi, the GPS, the Android OS and many more. Samsung Vibrant (and its versions) was and still is one of the most performing smartphones on the market, until the time will born new successors - till then, the choice is obvious.
