Engraving an iPhone knocks $25 off resale value

Good news : I looked up what the trade-in value is for my iPhone 4S 32Gig. Much to my pleasant surprise, it's $195. Almost enough to pay for my new iPhone 5S!

Bad news: If I hadn't stupidly engraved it, the trade-in price would be $220.

Word to the wise: Don't engrave.
