Sprint had told us in a statement that its BlackBerry Tours only had trackball issues on "early production" units, and now Verizon is telling us pretty much the same thing: Early on there was an issue with the trackball that affected a small percentage the early production units -- far less than industry norms. The issue was detected early, addressed immediately and is no longer an issue. Returns on this device are some of the lowest among any of our smart phones. In other words, it sounds like new buyers (and anyone who's taken the plunge recently) should be fine, and Verizon's actually taking it to another level by boasting that the handset's now one of its most return-proof smartphones
