    I have a 3gs jailbroken/unlocked. I tried this several times but still nothing! Can someone tell me what I might be doing wrong? Suggestions? Thx

      Perhaps it worked and you just can’t tell. This is what happened to me. Open your native text messaging app, click on a name/number to text, and notice on the bottom (to the left of the texting window) there is now a little camera icon. If you click on it, you will see the option to take a Photo/Video or choose an existing one. Hope this helps!
