Is there a way I can change my inbox so that every time i receive a new text, it will combine with the others from the same sender.. and not just be a new message showing the previous history. (like so it'll only be one per sender and not one per message) Sorry if i don't make sense

not possible

if you want that feature you are going have to get a Windows Phone as the Windows Mobile 6.1+ OS is the only one I know of that has Threaded SMS that works that way.
