A friend recently changed phone numbers on his T600 with sprint. After the switch, everything works fine except for SMS. He is unable to recieve them. When he sends a picture, it comes from the XXXXXXXX@messaging.sprintpcs.com new phone number address, but with SMS it comes from the old number! Is there a way to reset the SMS information?

basically, SMS is not sending from his new nubmer and this is causing problems. Any help would be greatly appreciated. i tried the communication forum, but no one there helped too much.
