RIM late Friday shot back at Apple's claim that its phones suffer from antenna problems as well. Co-CEOs Jim Balsillie and Mike Lazaridis said a demo of the BlackBerry Bold 9700 losing signal was just an attempt to draw RIM into Apple's "self-made debacle" and sidestepped the real issues caused by the iPhone 4's design. The two founders suggested they would have never used the frame as the antenna and that any BlackBerry doesn't need the same level of care Apple's phone does.
