Ok I and several of my friends have been having a problem with some of our contacts. It seems as though after we send the initial text message to a specific person, the phone automatically adds a +1 to the contact and will not allow us to respond to that person without starting a whole new thread with each message we send. I think maybe facebook is what is causing the +1 but even if I go in and set the number with out the +1 as the default number for the person, and unsync my contacts from facebook (that includes backing up the contacts to the memory card, clearing data from the contact storage and from facebook, and then resetting up facebook without resyncing the contacts and then restoring the phonebook). I still end up having to wipe the device in order to get the problem to be fixed. I have also tried deleting and readding the specific contact.. Anyone have any suggestions?
