O2 and Privacy
Those of you who have an iPhone might want to check the terms of your contract to make sure they are not the same as the O2 Mobile Broadband contract. Specifically look for something like this:
"15.1 You authorise us to use and disclose, in the UK and abroad, information about you, your use of the Services (including, but not limited to, phone numbers/email addresses of calls, texts and other communications "Communications" made and received by you and the date, duration, time and cost of such Communications), how you conduct your account and the locations of your Mobile Phone for the purposes of operating your account and providing you with the Service or as required under law to our associated companies or agents, any telecommunications company, debt collection agency or credit reference agency. You agree that the information may be used by other parties in assessing applications for credit from you and members of your household and for debt tracing, credit management and may be used by us or other parties for crime and fraud detection and prevention."
"15.2 You also agree to the information described in clause 15.1 being used, analysed and assessed by us, and the other parties identified in clause 15.1 and selected third parties for marketing purposes including amongst other things to identify and offer you by phone, post, the Network, your Mobile Phone, email, text (SMS), media messaging, automated dialling equipment or other means, any further products, services and offers which we think might interest."
Which is taken from O2's Mobile Broadband Terms and Conditions...
I expect they have similar clauses in the iPhone contract and if so, in essence, all your base are belong to O2...
