I have moved from the UK to the USA and have a new phone, I try to change my country location on the store and get an error message saying I have to cancel my itunes match and have a pass incomplete, any ideas?

iTunes match is a subscription that you have in when you were still in the UK. According to the terms & conditions you'll need to wait for the susbcription to end before you can change your country to iTunes Store USA.

(1) First go to the App Store on your iPhone and search for "iTunes" do not go into iTunes via the existing iTunes icon on your iPhone homescreen

(2)Then scroll down past all the music and at the bottom: in the far left or far right of the screen, you will see your Apple ID

(3)You click on this and you will see your registered credit card and address

(4) In my case: I am in Qatar, but I was blocked from downloading useful Apps from the iPhones Store- goodness knows why! , if you have credit card registered to a permanent address in the county of the iPhone Store you want to download from then , this will work...

(5) Change the credit card details/address and the telephone number

(6) You will then be able to go to the iTunes store of the ("new") country and download any App in that store

It is a real pain and a design constraint of the iTunes system, personally- I couldn't care less about the music, I like various Apps for online banking etc./navigation on journeys etc.

I hope this helps you!-Nael
