In reading this book, you may get stuck if you dont understand a few basic facts related to the iPad, or a few conventions that the Take Control series uses.

Software and hardware:

iPad and iPad 2: This book covers all iPad models shipped to date, including the original and iPad 2. The iPad 2 is slightly thinner and lighter, and somewhat faster than the original, and it has front- and rear-facing cameras. For the purposes of this book, the old and new units function alike.

iOS: iOS is the name of the operating system (OS) that handles all of the iPads operations, managing hardware and software. Apple formerly called iOS iPhone OS, which made increasingly less sense given that the iPhone, iPad, and iPod touch all use the operating system.

iOS 4 is an upgrade for all the original iPads, starting with iOS 4.2.1. The iPad 2 shipped with 4.3. All iPads may be upgraded to iOS 4.3 and later releases. Apples iOS 5, due in the third quarter of 2011, will work on all iPads as well.

GSM and CDMA: GSM and CDMA are the two most widely used cellular standards in the world. GSM is in far greater use, with AT&T in the United States and major carriers across Europe, Asia, and the Americas relying on it. CDMA is used by Verizon Wireless in the United States and by a few other carriers in limited markets. Apple originally released the 3G iPad in a worldwide GSM edition. The iPad 2 comes in separate models for 3G GSM and for Verizon Wirelesss CDMA network.

Radio types: All iPad models have Bluetooth and Wi-Fi radios. Bluetooth is a short-range wireless technology for linking audio headsets, wireless speakers, keyboards, and mice. Wi-Fi is a high-speed networking standard for moving data among computers and other devices on a local network.

The 3G iPad has two more radios: a cellular modem, which allows data communications on mobile networks, and a GPS receiver for calculating position based on satellite signals, just like with a standalone GPS navigator. The cellular modem may be for either GSM networks or Verizon Wirelesss CDMA network.

Information related to 3G networking is highlighted: I use a special blue box to call out information particular to the iPads 3G hardware and 3G service plans.

Desktop vs. mobile: In this ebook, a desktop device is either a laptop or a traditional computer that would sit on a desk, typically running Mac OS X or Windows. A mobile device means a portable or handheld computer-like device such as an iPhone, iPad, iPod touch, Android phone, Kindle, or Blackberry. Mobile software or a mobile operating system refers to software running on a mobile device, such as iOS or the mobile version of Apples desktop Safari Web browser, which is technically called Mobile Safari, even though Apple calls it Safari on the iOS 4 Home screen.

Navigating on the screen and in the menus:

Touchscreen: I often mention tapping an item on the touchscreen, such as tap the Join button. Occasionally, you may need to double tap, or even touch. Touching means putting your finger on the screen and keeping it there until something happens. You may also need to swipe or drag your finger across the screen.

Settings app: I frequently tell you to adjust options in the Settings app. By default, this app appears on the first page of the Home screen. To view the Home screen, press the round Home button on the edge of the device. To open the Settings app, tap its icon.

Navigation: To describe moving around in the iOS 4 interface, I sometimes use a shortcut. For example, if I wanted to tell you to open the Settings app, tap the Wi-Fi option at the left, and thenin the right hand Wi-Fi Networks panetap Other, I might instead tell you to tap Settings > Wi-Fi > Other.

Using an external, physical keyboard: Some directions assume you are using an onscreen keyboard. If you are using a physical keyboard, you may need to press the Return or Enter key to enter certain information, instead of tapping the Join or Search button that would otherwise appear on the onscreen keyboard.

Improvements in iOS with the release of 4.3 have been folded into this version. This includes network-related features, such as:

Apple has released Verizon Wireless versions of the iPad 2 that use Verizons less-common cellular network standard, CDMA. Information related to Verizons network has been added and updated throughout the book.

Service plan information for prepaid and postpaid plans for AT&T and Verizon Wireless has been altered.

, a topic that discusses alternatives to using a 3G network for iPad access, has been dramatically simplified due to improvements in using phones as mobile hotspots, and the addition of Bluetooth tethering to the iPad.

The chapter was updated to explain how and why to use Bluetooth tethering with an iPad to gain access to the Internet through a phone, laptop, or router.

I removed two chapters on apps for remote access and document access because of the rapid changes in apps in those categories and because of an apparent lack of general interest on the part of readers. Most of the former Access Documents chapter is covered in Take Control of Working with Your iPad .

Beyond the Verizon-related changes noted above, no changes were necessary for the iPad 2, which has minor hardware differences from the original iPad, but otherwise functions the same from the network and security standpoint.

The EPUB-formatted file for this new version was created using Take Controls in-house procedure, instead of outsourcing it, as weve done previously. The new look is now much closer to the usual Take Control styling. (Read , near the end of the ebook, to find out how to get the EPUB.)
