i have iphone 4 running ios 6.0.1 one of my contacts changed his number, so i went into the contact, edit and replaced the old number with new one. i wanted to send him an sms, so i went into sms, and i opened a new message and started typing his name. his name came up twice, once with the old number (that i deleted and once with the new number. if i chose the old number, i have a number not a name in the "to" of the message. i went into the messages and deleted the old sms conversation i had with his old number, then i went to contacts and deleted the contact completely and created it again with the new number. then i restarted the phone. however, still when i wanna write him an sms and i want to choose his name, i c the name twice: once with the old number and once with the new number, although i made sure the old number is not int eh contacts and when i search the contacts, i only see him as one contact with the new number. is this normal? can someone explain it?
