How can I remove a phone number from the recents list in iMessage? I can do it easily in mail.
The only way to do that is to restore the phone as new (not from a back up). There is a workaround to get the numbers from appearing by setting up a new contact with a nonesense name that you would never type and assign the number to that contact. Bit of a kludge but it seems to be sufficient for some people.
You may also want to submit feedback to Apple requesting that the add the same delete capabilities they've recently added for Mail.
Best of luck.
