ok i ordered a replacement glass panel for my iphone 4. i dopped it and cracked the back glass. the replacement i ordered from China is just the glass piece, theres no way to put it on my iphone 4. Theres no groves for it to sit back into the phone or anything, its just the glass piece itself. The package came with a mini flat head screwdriver, a mini screwdriver, and a little tool that looks like its used to pry open something. Does anyone have any idea how do i put it on my phone
