I have a new iPad and upgraded to iOS 6.
When I send an iMessage, it looks like I sent it from another person's phone. The picture is not my profile picture.
Why might this be?
Is the default number or mail address associated to iMessage stored in your contact card? If not this is the reason.
You can change the default sender by coning to
This phone number or email address will be the one used for sending iMessages. Hence, if this number is not associated to your contact, iMessage will not show your picture.
If all the available options belong to someone else, then check that the contact card for you is assigned correctly.
To change the picture go to Settings then Mail, Contacts, Calendars In the contacts section set My Info to your contact info
