Its annoying, with the money Apple makes annually, and the past experience of problematic issues, and the endless versions/updates of its beloved music library "ITUNES"...you would of thought something like this will not occur AGAIN?.
I only got my Iphone 4 last friday, and I love it so much, don't get me wrong Apple do make good phones and good operating systems, but when it comes to itunes, its so bad, that I don't think I have every really found it or said it was "good" to use.
But hey ho, thats my opinion, hopefully this is just a temporary problem, will try and access my Itunes store later and see if it works..keep you all updated.
