How do I erase recent text message contacts which are already deleted contacts?
I upgraded to an iPhone 5, and subsequently gave my son my iPhone 4 to use for games and messaging. His apple ID is still the same as mine. He has his own iCloud account however. We cleared my contacts out of his phone and they do not update with iCloud. However, If my son starts to write a text message to one of his contacts (there are only 5) and he types the first letter of the contact instead of using the + (add a contact from the address book), up comes all my old recent contacts even though they aren't listed in his current contacts. I don't want him accidentally texting my business numbers! How do I remove "recent contacts" from the messaging like I can from recent email contacts?
iPhone 4, iOS 6.1.3
