At its debut, the iPad offered a hardware-based screen orientation lock, while the iPhone used a software-based lock that was introduced in iOS 4. With the introduction of iOS 4.2, though, the hardware-based approach as removed from the iPad, leaving both devices to lock their screens in the same way.
