iPhone keeps prompting me to enter a password for an Apple ID that I no longer use
my phone keeps prompting me to enter a password for an Apple ID that I no longer use - it appears to be linked to iCloud , whereas my usual ID is used for iTunes and is fine.
The problem is I have no idea what the password is and when I go to iForget to reset Apple tells me it is not an Apple ID.
How can i remove it from my phone without wiping the whole lot?
