I got my iPod Touch 4 days ago and put on the InvisibleShield same day. I put the back on first just in case I messed up. Back ended up with about 4 big bubbles and they are slowly going away but definitely still there with the solition in them. The front only has 2 little bubbles, but is this allright? If so, how long until they're gone, I really only care about the front but it is annoying to feel the bubbles on the back.
