Iphone fell out of my pocket, hit the old street made of bricks. Shattered the front panel. Phone still worked, just couldn't see anything. I don't have a contract anymore, and am still on the ATT unlimited plan, so there was no way I was going to buy a new phone or have to sign a contract. This was the only option.
Took about hour & a half. Mostly because we had to remove all the tiny pieces of glass from the adhesive. And the suction cup didn't work because it couldn't get a grip on the front panel with all the cracks. Had to use the suction near the hinge area and use a tiny screwdriver to wedge up the bottom corner. The rest of the repair went well, but I think I need some way to seal the sides of the phone. But it works better than it did before. Much more responsive.
A small razor knife or blade ( and I mean tiny!) is helpful in removing the adhesive. But use carefully!
