That might be true with the glass back iPhones, but I wouldn't trust the finish on the aluminum to not come off with the sticker if it has been on there for a considerable amount of time. I could see after a year of use, it would be adhered very tightly and possibly take the anodized finish off the phone. Guess we won't know until someone tries it.
funny how people on this forum are always ready to bash other peoples likes. i am sure you all drive nice luxury cars that everyone awes over and wear the best designer clothes out there. someone is just showing something they like. no need to call him a 12 yr old or outdated.
