Wow, looks like it’s getting to be a very bad week for data security. First Microsoft and Co. lose ALL of your Sidekick data, then Apple has a pretty serious bug in terms of their OS and the possibility of data loss. Now from Apple’s MobileME service, there comes a report of data leakage – more specifically, someone has noted that during the registration process for me.com ( eg. upgrading your account ), they have had access to other users’ address book details! Scary – and doesn’t bode well for cloud computing services and all the naysayers that go with it.
