[bwatson90]

hi i bought my phone not long ago and want to change it around. i have the sprint touch pro and want to put a good looking background make my speaker function louder and do the button color change
i really need to know how to do this. if i need to download total commander and how to locate files and whatever else you guys think i should do. if i need to turn this phone into insurance ever will it void my warranty. also if it does how do i turn it back to stock. also how do i take this thing apart to do the button color change. one more thing i think my phone is slow if i can speed it up that would be great too, thanks brett
