I ordered an iPhone 4s on the 7th, got it on the 14th, noticed the next day that when it got warm there were issues with the screen. Made an appointment yesterday, walked in... had to wait 45 mins, but no big deal. Employee came up, shook my hand, took my phone, we talked over the problem, he ran some diagnostics, we joked around a little, he then went into the backroom, got a brand new iPhone 4s for me, we turned it on, checked it out, I signed a form, he shook my hand and I drove home with a functional iPhone 4s. I've never experienced a more pleasant customer service strategy. Well done Apple, well done.
