XCode and recent iOS SDK
<p>I am currently using <code>XCode 3.2.2 and iOS SDK 3.2</code>. With these I can produce binary which works on iPhone 3.1.3. If I upgrade to <code>XCode 3.2.4 and iOS 4.1</code>, would I still be able to build binaries for iPhone 3.1.3 device? If no, can I install both, or it's tricky?</p>
