I have a Samsung Blackjack and have found that all of a sudden I am unable to send pictures via multimedia message. I had no problem before, but maybe accidentally changed a setting without knowing so. The error message I get when I try to send a pic is "Unable to connect. Verify your profile settings and try again." Not sure if this is related to the picture size? However I have not purposely changed the sizing. I'm not sure where to go to change my "profile settings" or to check what it's set as. Appreciate any help. Thanks.
