replacement went ok. the guide with the young lady was not as detailed as another one i saw but couldn't it when i did the repair. there looked to be a protective plastic covering on the inside of the replacement glass. i tried to pull it off but it did not feel right/it did not peel back like the others did so i left it on.
i also noticed that your proceedure for identifing the type phone asked if it is a 3gs 8-16-32g. my phone does not show a memory size on the back anywhere. i assume that in the case of a front glass replacement memory size does not matter.
