<P> The iPad syncs with iTunes on a Mac or Windows PC . Apple ported its iWork suite from the Mac to the iPad, and sells pared - down versions of Pages, Numbers, and Keynote apps in the App Store . Although the iPad is not designed to replace a mobile phone, a user can use a wired headset or the built - in speaker and microphone to place phone calls over Wi - Fi or 3G using a VoIP application . </P> <P> On October 12, 2011, iOS 5 was released to various iOS devices, including the first - generation iPad, and was downloadable through iTunes . The update was reported to contain hundreds of new features and tweaks, including Twitter integration, Notification Center and iMessage, which is a feature that allows users to send messages or multimedia files to other users on iOS or OS X, the operating system for Apple computers . iCloud, an iOS app and Apple - provided internet storage service which allows users to sync and backup their user data and settings to / from other devices, was also made available through this update . On June 11, 2012 it was announced that iOS 6 would not be released for the first - generation iPad, making iOS 5.1. 1 the final operating system officially available for the device . </P> <P> The first - generation iPad features an Apple A4 SoC, which comprises a 1 GHz processor, 256 MB of RAM and a PowerVR SGX535 GPU . There are four physical switches on the iPad, including a home button near the display that returns the user to the main menu, and three plastic physical switches on the sides: wake / sleep and volume up / down, plus a software - controlled switch whose function has changed with software updates . Originally the switch locked the screen to its current orientation, but iOS 4.2 changed it to a mute switch, moving the rotation lock function to an onscreen menu . In the iOS 4.3 update, a setting was added to allow the user to specify whether the side switch was used for rotation lock or mute . Unlike its successors, the first - generation iPad has no cameras . </P> <P> The iPad's touchscreen display is a 1,024 by 768 pixel, 7.75 × 5.82 in (197 × 148 mm) liquid crystal display (diagonal 9.7 in (246.4 mm)), with fingerprint - and scratch - resistant glass . As a result of the device's screen dimensions and resolution, the screen has a pixel density of 132 ppi . The display responds to other sensors: an ambient light sensor to adjust screen brightness and a 3 - axis accelerometer to sense the iPad's orientation and switch between portrait and landscape modes . Unlike the iPhone and iPod Touch's built - in applications, which work in three orientations (portrait, landscape - left and landscape - right), the iPad's built - in applications support screen rotation in all four orientations, including upside - down . Consequently, the device has no intrinsic "native" orientation; only the relative position of the home button changes . </P>
