I dropped my phone (the day after i got it!!!!!) and cracked the screen. At first I thought it was only the glass and was planning on trying to replace it myself, but now I realize that only the top half of the touch screen in working. it looks fine, but i can use any icons on the bottom half so its impossible to answer calls or send messages. Is it possible that it's still only the glass, or do i definitely need a new digitizer too? is it even worth trying? it was only $100 phone so I'm not really willing to pay much to repair it.
