O2 puts unprotected MMS pictures on web, Google still caching phone numbers - Tech Digest
Over the weekend, it emerged that pages from O2's MMS-to-web service had been crawled and indexed by Google, raising concerns over the privacy of its customers' data. The system sounds innocent enough: if someone is sent an MMS message but their phone (such as an iPhone 3G) is incapable of receiving / displaying them, they are instead directed to a web page where the picture is displayed. This also includes the sender's mobile phone number and keywords.
