My launch-day iPhone began developing bubbles around thanksgiving. First one, then two , then three, then the fourth this weekend. I swung by my Apple store this morning and the Genius couldn't have been nicer. He told me that they are seeing more of the bubbles as of late, but they still don't know why they are forming. Policy from above is to just swap out any bubble phones with a new one on the spot. I was in and out of the store in about 10 minutes. Very impressed with this service experience.
