RIM greatly widened its smartphone mix on Wednesday with two more BlackBerry 7 devices. The 9850 and 9860 are the first touch-only phones from RIM to get a high-resolution screen: either has a 480x800 LCD that finally makes them competitive with modern Android hardware and more comparable to the iPhone. The two likewise drop the often criticized click-down SurePress screen from the Storm and use multi-touch instead, much like the Torch 9810.
