Howdy. Long time lurker with no knowledge to help anyone. Despite careful handling, a strange vertical scratch/abrasion has appeared on the edge of my 3GS's bezel, right close to the actual screen. It's not too big but right in view. If it was anywhere else, I'd use high grit sandpaper to sand it out. But being so close to the LCD, I'd be concerned about grit coming off the paper and lodging between bezel and LCD. Any ideas? Thanks.
