My son had his iPhone 6 stolen and it was registered on Find My iPhone. Within a day or so of the theft, my son put the phone in "lost mode" on the iCloud. About 10 days after it was stolen, while we were periodically monitoring iCloud to see if it ever got turned-on, my son changed his login name & password on iCloud. So now he has two devices (iPhone 6 & iPad) with the old name on them, with the corresponding passwords, and his iCloud account with a new name & a new password.
To add perspective on my question, even though his iPad had the old name & old password, it was located on his iCloud Find My iPhone map that had the new account name & new password. His iCloud would indicate when the iPad was turned on or off. What I'd like to find out is, since there appears to still be a linkage between his iCloud account and his iPad, would it follow that there would continue to be a linkage with his iPhone 6 (old name/old password) and his iCloud account. If the linkage continues, we would continue to monitor his iCloud in case the phone gets turned on; if not, we will of course just have to move on. Thanks very much for any help with this!
