We know that the BlackBerry Torch had been worked on for over two years. We now see images of one of the prototype devices codenamed Tardis, which was likely what we knew as ‘Mr. T’ in the very beginning.
As you can see it was running a variation of OS 5 that closely resembles the same OS on the Storm series. The OS version and platform on the Tardis are pretty strange, but its likely nothing that will impact the current Torch.
