I've had one small drop from couch to the floor. Nothing serious and no damage.
Using the Speck fitted cover, so not much protection either.
I know the day is coming though when I do drop it, try to catch it with my foot, and instead kick it 6 feet across the floor. It's only a matter of time
My 3GS, too much of times... The last time I dropped it the screen shattered "Beyond Economic Repair" so I called my insurer and said: "Hellooo iPhone 4!" That said, I'm pretty OCD 'bout not dropping the new phone.
Plenty, including flying out of my pocket when I came off my bike. Its a bit scratched and goes to 'no service' once or twice a week where I have to restart the phone since the bike, but other than that it works fine.
I'll get a iPhone 4 next month maybe.
Luckily i bought covers the same as apple's bumpers.
Something very cool happened to me though.
I went to Dion Wired and my i cought some Apple bumpers (not official Apple bumpers). The price labels on it said R20 i think, and couldn't believe that it's so cheap cause i saw other for like R200, so i asked the guy how much the bumpers cost.
He scanned them and told me they cost 5c!!!!!! Haha
I was stunned!
The guy asked me if i want more bumpers. He brought me a couple so i ended up buying like 7 of them!
Paid with a R1. Told them to keep the change haha
