"If you recently purchased the new iPhone and have experienced poor reception quality, dropped calls and weak signals, we would like to hear from you." That is the text from an advertisement placed by a Sacramento-based law firm that is attempting to put together a class action lawsuit against Apple (Nasdaq: AAPL). According to the report in Fortune, this is the same personal injury law firm that also sued Facebook (and game designer Zynga) because users received unauthorized charges for games Farmville and Mafia Wars.
