Hi, new here, and thanks in advance for all your help. I have a concern similar to "Motoservo." My iTunes ID is my full email address, but my phone (4S w/IOS6) originally had just my user name for the ID (it now shows the full address & accepts the current password). When I try to update apps that were acquired under the original ID, the prompt for my password will not accept any ID, either current or past. I have tried all of the fixes Motoservo and others, suggested (I didn't get the messages he/she did) and have gone so far as to restore factory defaults with no change, when I try to update, the screen still shows the old ID and won't accept any password. I do understand that the ID is tied to the app (it would be nice it the password was too).
Now, my iTunes shows that there are apparently updates to the apps in question on my computer, but so far no syncing, or any action I can find will let me transfer those updates to my phone.
Any thoughts/suggestions? Short of deleting the app and reinstalling it that is, (which I guess is the next option)?
Thanks again.
