Percentage users still on iOS 3.x? Should I bother?

Question

I know its been asked/answered before, but everything I look at is from back in July, or otherwise out of date.

Should I bother making my app compatible with iOS 3.x (probably 3.1.2 and up)? Means extra testing some coding changes, etc, etc.

Or are enough users on iOS 4.x that I don't need to worry about it.

If there are any sites that keep up to date (daily, weekly, even monthly) stats, please post.

You can confidently ignore 3.x now.

DO NOT BOTHER.

You will find no difference in sales. It's a 4 world as of xmas 2010.

Answer 2

A reasonable number of users are unable to upgrade to iOS 4.x and will remain forever in 3.x land because their phones are pre 3G. Specifically many users in countries without access to the latest smart phones will still consider a 2G iPhone to be modern. I'd recommend launching with iOS 4.x and adding support if your user base desires it (and if your app gets traction, it is a very competitive market). As an aside, the iPhone (2G) were on sale until mid-2008; many users are still under contract on a device and unable to upgrade! Poor souls!
