title: regarding check for base sdk in application code
body: <p>I want to check if a particular device is having base sdk 5.0 or 4.3 or 4.2 or any other iOS sdk version. To put it more clearly, I want a particular code to run only and only if the iOS sdk version is 5.0 (using the APIs only supported in iOS 5) and if it is less than 5.0, then I want a different code to run. Does anyone has any idea about this???</p>
