With the help of some posts here on hackint0sh, I pulled apart my iPhone 3G to replace my broken glass/digitizer, but when I got it back together, the screen wouldn't turn on and it won't respond to touch commands (for example, I pressed the home button and ran my finger along the bottom of the screen - no response). The thing is, it beeps when I plug it into a charger, iTunes recognizes it when I plug in USB, and it vibrates when I move the silencer switch. Strangely, it also rings when I get a text message, but not when I receive a phone call (on the other end, it rings a few times then goes to voice mail).
I think I exerted a little too much force on my LCD when I was disassembling it, so that might be part of the problem, but the only visibly affected areas are on the bottom - I expect the rest would still work or at least pass some light through.
Any help would be appreciated!
