not an iphone user but for those doubting the privacy implications i’ll give you an example.
when my CC and bank card were cancelled recently (thanks crc) the only way i could get cash was to go to the bank and get it over the counter. two of the security questions (and therefore 33% of what HSBC deems to be suitably secure) were asking where i had travelled abroad recently, both places i had used my phone.
fair enough, as an individual database it’s a fairly harmless block of data to anyone but those with a specific agenda, however, pool data like these with all the other easily available (and not so easy) data stored in all sorts of places and linked to you by various things like CC numbers and social networking etc and you have a growing and worryingly accurate picture of your life available to people, most importantly over which you have no control. it’s not about having nothing to hide, it’s about having the choice over who has access to the information and for what purposes it is used, something we commonly don’t consider. that said, everyone has something to hide.
