T-Mobile has officially lowered the price of two of their newer Android devices, the Samsung Galaxy Tab tablet and the Samsung Vibrant smartphone. The new lower pricing is currently in effect and means should you purchase either device you will be spending $50 less than you would have a few days back. Bottom line, the Galaxy Tab is now $349.99 and the Vibrant is now $149.99. And yes, both still require a two-year agreement. With that, T-Mobile has left us all to wonder whether these are permanent or holiday related price drops.
