Maybe this question applies more to people with no case. 4/4S uses steel/aluminum bezel while the 5 uses aluminum on the back side and the bezel as well.

Just curious if anyone has seen any rust because of the dings or deep scratches

Thanks.

I've never heard of anyone experiencing rust. Aluminum is what the metal parts on the case of iPhones are made of and that material does not rust. Aluminum can corrode over time, however, it would take a while and lots of elemental exposure for corrosion.

I see, thanks for the response. The reason I ask is that I know of an expensive watch that uses an anodized aluminum as its case and case back material and it experiences rust on certain corners of the watch (mostly happen in the case back where you see the thread which is invisible to users unless the watch is open and look at the case back). Not all of the watches have rust, but some of it do, and people are not that happy as they pay a considerable amount for the watch...

There is no rust on any of my i-devices.

With a watch you most likely will experience sweat which will help rust the watch

No rust here. I don't think I have ever heard of this issue.

Never seen rust on any iDevice.

I've had iPhones going all the way back to the first generation and none of them have ever rusted. None of my friends iPhones or iDevices have ever exhibited any rust either. Nor have I ever read any posts on any forums about anyone experiencing rust on their device. Some of my iPhones have been caseless, some (like my iPhone 5) are cased.

I had a bit of corrosion on the bottom two Phillips head screws on the ip4 . It was barely noticeable

Can you go to Apple Store and ask them to replace the screws for you?
