Drop iOS 3 support

[sindresorhus]

I propose ShareKit drop support for iOS 3.

iOS 3 was released summer 2009 and most people have upgraded.

Also, ARC requires at least iOS 4, if we want that in the near future.

There's at least one person using ShareKit on iOS 3 (see #147). On the plus side, dropping iOS 3 support would resolve that issue.

Are there any places in the code where you think the iOS 3 support is holding us back?

I am strongly in favor of dropping iOS 3.x. I stated that also in #147

I'm indifferent to keeping iOS 3 support around or not, however since currently there are only three pretty minor issues holding it back, it doesn't seem like it would get in the way of anything or be much work.

Yes, now we can cure the issues somehow. But the problem can be in future changes. I wonder if some people still have iOS 3 device around? And time to test on another environment, of course...

@scompt Not that I know of, but haven't really read the source, though there is probably some things that are deprecated now, better ways to do things, conditionals, etc.. Also current and future bugs, ARC, Blocks, ...

Marco Arment published some stats from his app Instapaper in November. It shows that 98.8% of his users have at least iOS 4.0. He recently set the minimum version to 4.3, with only one person complaining. Instapaper is a very popular app.

Another problem is that the iOS simulator in Xcode 4.2 doesn't have iOS 3, so we can't really test ShareKit on iOS 3 without a real device running it. And like @VilemKurz asked; does anyone still have an original iPhone/iPod touch?

We need to cut the cord sometime, why not know?

4.0 support added in prerequisites, closing
