Apple is accused of aiding and abetting the intentional taking and transmitting of user data to third parties. The suit also names Pandora Media and The Weather Channel, but leaves the door open to name more defendants at a later date. Suit is based on concerns raised in a Wall Street Journal report over mobile apps sharing user data with third-party advertisers. Apple recently updated iOS to version 4.3.3 to deal with some complaints about the location data cache on iPhones and iPads.
