I've read other threads, and I'm not going all OCD and rushing off to Apple to demand a replacement (I'm out of warranty anyway, not that it matters). I have the orange Apple bumper, official one, and after using it today while out for a couple of hours, I removed it upon getting home and noticed that there's two little polished marks on the band. I cleaned the band and wiped inside the bumper before applying it, but even when checking the bumper for rough areas, I can't feel anything that would continually rub and cause these little markings. I used it again around the house for an hour or so tonight, and again after removing the bumper, the polished spots look a little more pronounced. It's only in this one little area, but while I could just keep the bumper on permanently, I don't really want whatever the hell it is continually rubbing away and causing more noticeable damage. Is there anything out there, available in the UK, to cover the antenna prior to applying the bumper? Cheers.
