Microsoft's Pure and Turtle media phones have been given more tangible details thanks to the discovery of their firmware and the image creator that makes their firmware possible. The Sharp-made phones will be far from the specs needed for Windows Phone 7 and carry resolutions of 480x320 for the larger Pure and just 320x240 for the squat Turtle. Both will still be at least moderately quick using some variant of NVIDIA's Tegra, though whether this is the original or the dual-core Tegra 250 isn't known.
