title: What should be minimum deployment target set for iphone application while releasing it to App strore?
body: <p>Hi I am new to the iPhone App development. Currently I released a small application to App store having deployment version 4.3. But some users are not able to download and install the app due to version compatibility. I searched on internet but I didn't get much solution. Now what version should I set while deployment so that every user can use the application?</p>
