A US District Judge, Edward Davila, has thrown out a class action lawsuit filed on behalf of iPhone 4 owners. Initially launched by Californian Betsalel Williamson, the suit complained that Apple misrepresented the strength of the glass in the device. Williamson says that after knocking a new iPhone 4 off the arm of a chair, the device broke, "resulting in spider cracks across the back glass panel" which forced him to get a replacement.
