Getting rid of old Apple ID
When I bought my iPhone 4S I was with BT for internet etc. I subsequently changed to Sky (although now back with BT) my Apple ID was ..........@btinternet.com and then subsequently changed to ......@gmail.com. However, on my phone (an iPad) when I want to update my software it keeps going back to my old BTinternet ID although under settings my Apple ID is shown as ..........@gmail.com (i.e. my current ID). Can anyone tell me how I can get rid of my old BTinternet ID please. I have tried everything including a complete reset.
My main problem is that I can't update anything as it keeps asking for my original Apple ID password which I no longer have.
iPhone 4S, iOS 9.2
