Earlier on we reported that the Blackberry 10 N-series was caught on camera (once again), and according to a post on 4chan, images of the Z10 and the N-series have been spotted side-by-side, along with another Blackberry device that we can’t help but feel is reminiscent to the HTC Facebook phone. Given that Blackberry 7 devices are available in different tiers, like the Torch, Bold, Curve and etc., we wouldn’t be surprised if RIM had plans to do something similar with Blackberry 10 devices. While the poster claims that the handset on the left is the white version of the N-series, we beg to differ as the keys are somewhat similar to the Curve series of Blackberry 7 handsets. Could this be the Dev Alpha C device that RIM had recently given out to its developers, or are we looking at a possible final design of another Blackberry 10 handset? Let us know what you think in the comments below!
