ITunes Music and Home button not responding

Question

Itunes Music & Home button not responding all other content OK when music button clicked displays the following "The item you've requested is not currently available in the UK store"

Answer 1

I haven't read this whole post - in fact I almost stopped reading any of these post. I read all the horrors look over at my own phone (which is working correctly at the moment) and wonder when it is going to go belly up.
jyoz, Try doing a DFU and setting up as new. I don't believe that "Restore" goes deep enough to clear the bad code.
Do you also have poor battery life?
The reason I ask is I am starting to believe there is a piece of code that is corrupt and running at near 100% CPU usage.
If this is the case it sort of explains button, icons and poor battery life.
There is one other suggestion that I have read that says delete all email accounts and reset/erase all. Then go to DFU and setup as a new phone. This procedure probably gives you the best chance of clearing out the Bad Code Snippet. Just to defend all this crap that we have to go thru I did get an Apple/at&t support guy tell me that even "Push" on email is/does not always work correctly. Once he realized what he said I could not get him to talk about it anymore - Apple you gotta love-em.
I know you have been thru hoops trying to fix this but you only have two option take it to a store and don't leave until you get a new one that they have updated to 4.1 for you or try some of the extreme suggestion that I am repeating from other post.
Best of luck - and please remember sometime there are failure that you at home are just never going to fix - so if you don't feel like another Excedrin headache GO TO THE STORE AND EXCHANGE IT if for no other reason than to preserve you mental health.
