Error 5107
Cannot change country and payment details. Always get message "session expired, error number 5107"
iPad 2 Wi-Fi + 3G, iOS 6.1
i have the same issues when i want to change from chin to Hong Kong , i tried to change to another country "iceland", and try to download, update apps again.
apple returns saying my country has become iceland.
which leads me to think that error code is shown but the country code change has actually updated in apple record.....
so.. i just take this error code as a confimration of my change has been effective. hope this helps
