Dad always said that you'll never get anything you don't ask for, and that maxim is now proving true at the Apple store.
Apple stores are now matching the $50 discount that Sprint is currently offering on all models of the iPhone, dropping the price of the iPhone 4S to $150 when you sign a two-year contract. This is not an advertised or official deal: You can only get the discount if you specifically mention the Sprint sale, at which point an Apple store employee should price match. (We called an Apple Store here in New York and the representative did, indeed, confirm the price-matching policy).
