Some Apple iPhone, iPad ,and iPod Touch users are experiencing a problem when they select a contact where the Edit button is missing from the upper-right corner of the screen. This problem has occurred for many users after the iOS5 update.
To solve this problem, you will need to merge your contacts with iCloud by performing these steps.
- From the home screen, tap “Settings“.
- Select “iCloud“.
- Switch “Contacts” to “On“.
- When prompted, tap the “Merge” button.
Once this is done, the “Edit” button should then return to the upper-right corner of your individual contacts.
