Apple has posted its new User Guide for the iPhone 4 and iOS 4 online (PDF Link). The 28-chapter, 200+ page guide covers a host of iOS 4 features—including syncing and file sharing, all the core, pre-installed applications, iBooks, Nike + iPod functionality, and accessibility. Notably, the Guide includes several iPhone 4-specific notes and illustrations, including those for SIM card installation, high-definition video syncing, putting a call on hold—you press and hold the Mute button on the iPhone 4’s call screen—placing a FaceTime call, switching between the device’s two cameras, and a note stating that movies rented on the iPhone 4 cannot be transferred to a computer as on the iPhone 3G and 3GS; although movies rented on the computer in iTunes can be transferred to an iPhone 4 unit.
