I know that parts of this question was asked in several variation but I want to make sure I got it right.

Here are my assumptions and understandings which I want to know if they are correct before submitting.

My application assumes features supported by all OS, and so I should:

  1. Set the Active SDK to be the latest (currently SDK 3.0).
  2. Set the Deployment Target to be the lower I want to be supported - iPhone 2.0 and higher?
  3. What exactly is the Base SDK for? should I ignore it if I chose Active SDK to be different and where do I see the Active SDK in the Projects settings?

One final question - is apple allowing to choose iPhone OS 2.0 as the Deployment Target?

Thanks in advance,

BTW - one of my main reason for this question is because when compiling with earlier SDKs apple seems to have a problem releasing the memory for UIImageView animation array when this animation was saved for multiple time usage. This is a known problem that was fixed with SDK 3.0 (by simply setting the UIImageView animation array to nil)
