Im still using an iphone 2.x sdk (not sure of the exact version). Which version should I be using? When do we have to install 3.x?

Thanks!

You should use the latest version of everything; apps must support OS 3.0.

We are developing Unity iPhone to support iPhone SDK 2.0.

Which one SDK to install on your Mac mainly depends on your test device OS version. If your device is running OS 3.0 then you need to install SDK 3.0.

Another question is what SDK version to set as compilation target when building your Unity generated XCode project. We recommend to set lowest SDK version as compilation target to support widest userbase unless you are using some specific features of new iPhone OS’es via your custom code or third party libraries (like Enhancement pack).
