I'm really curious to see how Apple addresses this issue. It seems like it's becoming a pretty widespread issue and Apple may have to give out replacements..
But what about a month from now? Two months from now? The Apple store employee could EASILY say this is from normal wear and tear, therefore we cannot replace it.
In other words, I think Apple's either going to have to accept a lot of exchanges/returns, which would hurt revenues/profits and the stock's share price, but satisfy a lot of customers on the customer service front, or place a cutoff date after which you cannot exchange/refund your iPhone due to 'scruffing' issues, which would probably piss off a lot of customers.
Almost seems like a lose-lose situation 🙁.
Good luck, post-Steve Apple.
