PPCGeeks - Enableing ang useing mms video and other camera modes

i asked this already on another post but i thought that if i started a new thread someone else might see it and be able to answer me.

i have a question.i enabled every mode on my sprint tp and now i have
Photo | Video | Panorama| MMS | Contact Picture | Burts | Picture Theme | Sport | Video Share | and gps Photo | but i cant get mms video to record. it says 00:00:00 on the top next to the X and when i hit record, it tells me "unable to capture video. Disk Full." but ican capture video in regular mode.

video share lets me record, but then in the preview window, where the phone and tape is in the bottom right it wont let me click it. (what is it for) and what is video share mode for.

last but not least gps photo. it initializes th egps the ntakes the picture and saves it to my storage card. but then what does it do. what is the point of that mode to and how do i use it.

how do i use any of those modes and for what.](*,)
