My iPhone 4 is scheduled to be delivered on July 2. There is one reported problem that is making me think about either selling it or just returning it and that's people reporting that it's easy to scratch. Some say easier to scratch than the 3GS which should have the same oleophobic coating. What do you think? I'll be using a case that protects the back so I won't have to worry about the back getting scratches or signal issues. My 1 year old 3GS' screen is in pristine condition even under strong direct sunlight. I've never had a screen protector on it nor do I plan on using one on the new one.
