I have a 16GB white iPhone 5 & I have only had it for less than a week now. I have noticed that for whatever reason, my phone will not send picture messages. It will fill the "sending bar" to about 85% and then say "not delivered." And I'm "NOT PLEASED." I can't send group messages either and would like to know what is going on with my phone. I have already tried resetting my general settings and that did not work. Any help is appreciated. I think it's ridiculous that it's acting up seeing as how I haven't even had the time to get used to it. You're slacking Verizon.
