Small investigation
I made a small investigation of iOS device and version usage.
I did not count devices older than iPhone 3G and iOS older than 3.2, but according to http://www.marco.org/2011/08/13/instapaper-ios-device-and-version-stats-update their part is lesser than 2%.
Here are the results:
iPhone devices statistic:
Only 6% users use iPhone 3G and 2-th generation iPod and the major part (3/4) maiden up by iPhone 4/iPhone 4S.
iOS version statistic:
Almost 3/4 of users switched to iOS 5 as well.
So I think that the conclusion is simple: if you are not Facebook or Google and if you have no enough resources to support older iOS version, drop of the support of old devices and iOS version. Do not waste your time and efforts to support iOS older then 4.0 and to optimize your code to run smoothly on device older than iPhone 3GS. Or read this perfect article by Joel about drums and software optimization.
I picked up and accordion and do not regret.
