LinkedIn mobile app subscribers may be surprised to learn that calendar entries on their iPhones or iPads are transmitted back to LinkedIns servers without their knowledge. That practice, which is not communicated to users, may violate Apples privacy guidelines, which expressly prohibit any app from transmitting users data without their permission. A similar practice came to light earlier this year when a developer noticed that Path, the popular mobile social network, was uploading entire address books to its servers without users’ knowledge. The findings may shed more light on how technology companies take people personal and private information.”]
