I have OS 10.6 on my mac. I started with iphone SDK for snow lepard which builds for SDK 3.0 to 3.1.2. I'm ready to submit my app to the store. I'd like older iphones t开发者_C百科o use it as well. I can't find Apple's link for SDK 2.2. Only the link for the 3.1 sdk.

Do I need to release the app built with 2.2 ? If so where can I find it?

Can iphone users update the OS on their phones?

Thanks,

Actually, on my mac, (10.6.2) iphone sdk will build 'down' to 2.2.

And yes, iPhone users can upgrade (and downgrade) their OS. -- but you knew that since you've got an iPhone for testing right?

In the XCode, you can either specify which SDK to use to build your application or which OS version to use to test your application. See this guide for more details.
