still cant send picture mail

[GaJetski]

i know there have been PLENTY of posts on this topic but still no answer! i can recieve picture mail in my texts and it comes up with the url that takes me to sprints picture mail website. the problem is when i try to send! ive downloaded the cab to gain the mms function and even tho it allows me to attach images, it wont let me send to phone numbers, just email, so it really isnt mms? i upgraded to the official 6.1 but i havent tried pic mail before i did it. its bs because i get unlimited pic msgs with my plan and the phone dosen't even have the feature enabled! please help.
