Samsung's UAProf files reveals that something is cooking inside, as a new device with model number SGH-T999 spotted in the collection. However there was no information about the official name of the device. After some trial and error, the source confirms that this is nothing but Samsung Galaxy S Blaze 4G, a high end smartphone for T-Mobile. The specifications so far we know is that it will sport 1.5 GHz dual core processor power, a Super AMOLED display at 720p resolution, a 42Mbps HSPA+ radio. We don't have any idea on when the Samsung Galaxy S Blaze 4G is going to hit the stores of T-Mobile. The carriers says that they will be offering the device 'later this year.' So just wait for the Blaze effect. Source
