But a new version of the iOS isn't entirely positive for everyone. Every time Apple releases a major new iOS version, owners of older models of the iPhone, iPod touch, and iPad hold their breath as they wait to find out if their device is compatible with the new OS. Sometimes the news is good: their device is compatible. Sometimes it's mixed: their device can run the new OS, but can't use all of its features.
