The wife recently got her iPhone replaced on the insurance, however today she now has an issue in which she cannot turn her wifi on, the button is greyed out and we can not get it back on, having looked further into this there seems to be an issue with iPhone 4S phones which have updated to IOS 7 in which they are overheating and breaking the wifi chip to which they are unable to use wifi on the phone, wonder if that is what has happened to the wife's iPhone, we have a Genius Bar appointment on Monday so we shall see what Apple say, anyway she is not happy at this to say the least.
Here's the link with the article on this developing problem.
