first of all, how do i get my memory stick slot to open? it doesnt explain it to well in the instruction book, and ive never seen anything like this before, its not like my other phones, where you just peel away the cover for the mem stick slot. how do i do it? btw, is there any quick and easy way for me to unlock this phone? without me having to go and pay $60 dollars at some store for them to do it?
