Software from Apple and Apple-approved third parties can be downloaded from the Apple App Store, which now offers more than half-a-million Apps, including games, productivity programs, educational programs, GPS navigation, social networking and many others.

The latest model, the iPhone 5 has an 8 megapixel camera which supports high-resolution video recording and face detection. It has an advanced  natural language voice control system called Siri and is available with 16, 32 or 64 GB of memory.
