I signed up here specially to share what happened to me when I bought my unlocked iphone 4 in Paris last week. I'd bought my shiny new toy and was playing with it the very next morning at a sidewalk cafe where I found free wifi when unexpectedly it slipped out of my hands and bounced off the pavement from a height of about 3-4 feet. What scared the *** of me was the fact that it wouldn't turn on at all after that. I thought I'd just poured 629 euros down the drain as I doubted I could just take it back and replace it because one of the plastic corners was all chewed up and scratched - it was obviously it had been dropped and it was also painfully obvious that this material that had been touted as super durable and scratch resistant was all a load of BS. Fortunately, when I got back to my hotel it started up again as soon as I plugged it in. So if you DO drop your new phone and it doesn't start, don't panic. Try plugging it in and if it still doesn't start, THEN panic. Now everything seems to work fine, except for the ugly chewed up corner which I've managed to hide with a silicone case which I realize now I should have bought from the beginning. So, keep in mind that without a case this sleek shiney glass stuff makes the phone as slippery as a fish and that if you DO drop it it will easily scratch or worse break as I've now seen in numerous places on the net. It's really fragile and delicate, so please do yourself a favor and get protection!
