It has recently come to my attention that Apple have been very clever with IOS6.
Funnily enough unless I had stumbled upon this article I would never have seen it hidden away in the depths of the menus.
To summarise the link, Apple have changed its stance on targeted advertising after making it difficult for developers to utilise it earlier this year. Since the introduction of IOS6 you now need to opt out of targeted advertising although it wasn’t the easiest thing to find. Thankfully the author of this article explains in detail how to do so.
