Iphone 4 broken.is this fixable?

I had it in my pocket in the gym and rest some dumbells on it on accident. The glass screen isn't cracked but i think the graphics card broke (not sure though). All you can see is a bunch of red lines on the screen.

You broke the digitizer. Can get a new one off ebay for $12 if you are confident of repairing it yourself.

  • Shattered iPhone 4S screen fixable? Three days ago me and my boyfriend got in a fight and he smashed my phone on a stone wall resulting in the screen being completely shattered. The screen itself doesn't work or show any image it's completely blank so I thought it was broken… Until someone tried calling. My phone still rings the screen is just broken. My brother knows someone that can replace the screen for $60 but do you think the screen itself is fixable?
