Re: Contact data will not update properly.
If I understand this correct, your trying to see a text message with/from a new number but do not want to delete the old message string just edit the old number to the new one. but keep the string. I might be wrong but the phone thinks the new number is an error and states so. It may work if you just add the new number as a new contact and and leaving the old name there add a new one such as ( old ) Fred to ( new ) FredNew. You did say when the new number sends everyone gets the message. So to keep the old messages the new number needs to be added but with a different name..
old , old, old, (edit add ) new and old, new and old, new and old
That's the only thing I can think of.
