According to BGR, Research in Motion has canceled all plans for every BlackBerry smartphone, other than the "BlackBerry London," that is currently under development. The company has apparently halted work on other smartphones that were under development, including the BlackBerry Milan and Colt. 

The report claims that the Milan was not a next-generation BlackBerry 10 OS device, but instead a BB 7 OS smartphone and carriers weren't very interested in a phone so similar to the current BlackBerry Torch. The Colt had already been canceled by Research in Motion for other reasons. 

Canada-based RIM is currently working to find carriers who are interested in the BlackBerry London.
