I was all set to trade in my old iPhone 4 with cashinmyfone.com (£296 for 32GB), for the bit extra I might get on eBay it didn't seem worth the hassle - probably 50% of the iDevices I've sold on eBay the first buyer has either been a non-payer or someone trying to scam me.
However, I had a look at what they were going for on eBay today and prices still seemed pretty high so I thought I would chance it. Took my free Apple bumper off for the first time ever to take some photos to show how pristine my iPhone was, and found the bumper has scratched the metal sides really badly, especially round the corners! I had heard a few complaints before about bumpers doing this, but hadn't really taken much notice. It's pretty bad though that the unprotected part of my iPhone 4 is spotless, but the bit which I entrusted to Apple to protect is a mess.
Guess it's cashinmyfone.com then!
