What is the minimum OS version with sdk 4

[phil1337]

Hello everyone

I am using xcode 3.2.3 and base sdk 4. Under the deployment section it's possible to specify the minimum version for deployment.

Are there any problems if I specifiy e.g. version 2.0? Does this have any impact on my software e.g. that the app runs much slower or something else?
What is the recommended setting, if there is one, for deployment target with base sdk 4?

Thank you in advance

Regards

phil

I'm pretty sure Apple only allows v3.0 and up now. I'm sure there was a press announcement about it a while back.
