Whenever you support an earlier OS, you should always have that earliest and all intermediate SDKs available, and you should make it a standard practice to build your products against those SDKs at least before releasing to customers just as you do an analyzer build. This will help you identify many of the cases where you need to safeguard against the use of unavailable APIs, methods, and classes. Oh, and you really should be turning on and listening to practically every warning possible. Then, after you do all that, testing definitely should be done.
