Taking in your iPhone 5 for the sleep button fix but really want to upgrade to an iPhone 5s? There may be a $350 trade in for you!

If you're taking your iPhone 5 into an Apple Retail Store to get the faulty sleep/wake button fixed then you might just have another option available to you — a $350 trade in towards an iPhone 5s or iPhone 5c. That's $80 more than is usually offered. There is one catch though — you have to ask for it. So what's the deal? Dan DeSilva, writing for 9to5Mac:

Apple employees have been instructed not to present this option unless the customer specifically asks about upgrading to a newer model. This policy is presumably in place so customers don't get the feeling that Apple put this program into place as a way to lure iPhone 5 users to upgrade with new contracts.

It's only valid for iPhone 5 devices that are otherwise in working order and don't have obvious damage like a broken screen. If there is other damage, you'd have to get that fixed first.

If you've been looking for extra incentive to upgrade, however, you have it. If you're waiting on the iPhone 6, though, then you may want to save any trade-in or upgrade opportunities for the fall...

So, anyone taking Apple up on the offer?
