nail glue problem
So a while ago, my grandma gave me one of those stickers that goes over the home button, and she said it wouldn't stay on unless she glued it down with nail glue. However, she glued the button on crooked and I managed to get most of it off, but now there's just one small piece thats stuck in the glue. I don't wanna take any chances with acetone, but I don't know what else to do. Do I have to take it to apple and get it fixed or is there another way? Because where I live, there's no Apple stores nearby, the closest one is probably hours away.
