Just two days after offering a $25 gift card when purchasing an iPhone 5 on a two-year contract, Best Buy has improved their deal on Apple's latest smartphone. They're now offering $50 off all iPhone 5 models from Verizon, Sprint and AT&T.

It doesn't appear to be possible to take advantage of the $50 discount while also receiving a $25 gift card and there's no indication how long this deal will last.
Update: Dealnews notes that Best Buy is now offering the $50 discount with 5,000 Reward Zone points (equivalent to a $100 Best Buy gift card) on the 16, 32, and 64GB iPhone 5 models. Free shipping, online orders only.
