СКАЧАТЬ You see a banner across the top of your iPhone’s screen. You can choose to respond or ignore it. You can ignore the banner, and it disappears in a few seconds, tap it to open the app that wants your attention, or in apps that offer interactive notifications, like Messages or Facebook, swipe down to respond. For example, an iMessage comes in while you’re reading the news on Safari; pull the banner down and a field opens so you can type your response, tap Send, and then return to the article you were reading, without ever having left Safari or pull down on a Facebook banner, tap Like or write a comment, and then return to what you were doing. iPhone saves notifications you don’t respond to in the Notification Center, which you can see by swiping down from the top of the screen. You choose which apps you want to see in the Notification Center and how you want to be notified in Settings, which we cover in Book I, Chapter 4.

      When a new app has been installed or an existing app updated, a blue dot appears to the left of the app name under the app icon.

Making Connections

      Your iPhone has the ability to connect to a variety of signal sources, which means you can be connected to someone somewhere all the time: to the Internet via your cellular carrier’s data network or via a Wi-Fi network, or to other devices like printers, keyboards, and hands-free headsets using Bluetooth, and to other iOS devices or Macs using AirDrop, which transmits over Bluetooth or Wi-Fi. To help you understand all your iPhone’s many connection options, we’ve organized those options into three sections: cellular and wireless connections; Personal Hotspot, tethering, and AirDrop; and lastly, Bluetooth and GPS connections. You can manage these connections in the Settings app.

       Cellular

      When you activate your iPhone with a carrier, you gain access to that carrier’s cellular voice and data network. Without boring you with too many technical details, your iPhone typically connects using one or more of the following protocols:

      ✔ LTE/4G: Long Term Evolution is the most recent cellular communications protocol. Both GSM- and CDMA-model iPhones can access the LTE network where it’s available. This may be referred to as 4G when a GSM carrier accesses the 4G UMTS network.

      ✔ GSM (Global System for Mobile Communications) models

      • 3G/UMTS: 3G is the third-generation protocol standard that uses the UMTS (Universal Mobile Telecommunications System) cellular frequency. This protocol is faster than EDGE, but consumes more battery power. If 3G is on but unavailable, iPhone defaults to EDGE.

      • EDGE: Enhanced Data for GSM Evolution is the first-generation protocol standard for connecting to the Internet over the cellular carrier network. EDGE often offers a more stable, albeit slower, connection than 3G because it offers wider network coverage.

      • GPRS: General Packet Radio Service supports both second- (2G) and third-generation (3G) cellular telephony. Usage is based on volume rather than time. If neither EDGE nor 3G is available, iPhone defaults to GPRS.

      • HSPA+: High-Speed Packet Access is a faster type of 3G.

      ✔ CDMA (Code Division Multiple Access) models

      • EV-DO: The Evolution-Data Optimized is a 3G or third-generation protocol, similar to UMTS for access speed.

      • 1xRTT: 1x Radio Transmission Technology is an alternative 3G protocol.

      Unlike GSM-model iPhones, if you have a CDMA iPhone and are actively transferring data over your carrier’s cellular network – to check your email or browse a web page, for instance – you cannot also engage in an active phone call while those data-related activities are underway. Any calls you may receive while using your cellular carrier’s data connection are sent directly to your voicemail. You can make and receive calls while doing those data-related things on your CDMA iPhone if you’re connected to a Wi-Fi network.

      

When your iPhone is connected to the Internet with one of these protocols, the associated icon appears in the Status bar, as mentioned earlier in this chapter.

      If you happen to be outside your carrier’s network, you can try to access the Internet through another carrier. This is called Data Roaming and is enabled by opening the Settings app, tapping Cellular, and tapping the Data Roaming switch on.

      

Data roaming, especially if you’re out of the country, can rack up sizeable surcharges. Check with your carrier for data roaming fees before being surprised with a whopping bill at the end of the month.

      

If your cellular carrier contract has a data transfer limit, you want to keep track of how much data you’re consuming. Your carrier may have a dedicated website or app that tracks the information for you or you can monitor your cellular data usage by opening the Settings app and tapping Cellular. Scroll down the screen to see the Call Time and Cellular Data Usage, which indicate the number of days and hours you spent on your iPhone during that period and during the total span of your relationship with your carrier plan and the amount of data you’ve shuttled back and forth over your cellular carrier’s network. At the very bottom of the screen, you find the Reset Statistics button that resets the aforementioned stats so you can start tracking those figures.

      You should tap Reset Statistics at the end of the month or on the day when your period renews. Using Wi-Fi for data access is an alternative if you have free or low-cost Wi-Fi service in places where you use your iPhone.

       Wi-Fi

      You may want to say that cellular is wireless, and you’d be right. But Wi-Fi is wireless, only better. Connecting to the Internet using iPhone’s Wi-Fi feature is one of the fastest – and cheapest – ways to connect to the Internet. Wi-Fi networks blast their typically close-range signals from a device known as a wireless router, which is connected to a broadband modem, which in turn is typically connected to your cable or phone company’s broadband Internet service (or whatever the Wi-Fi router you tap into is connected to, be it at your favorite cafe, on a train, or a public library, for example). Other people can connect their Wi-Fi enabled devices as well, making the group of you a network, as opposed to a single connection. You may need a password to access a Wi-Fi network, and some Wi-Fi services charge an hourly or daily fee to access their networks.

      To join a Wi-Fi network, follow these steps:

      1. Open the Settings app and tap Wi-Fi.

      The Wi-Fi Networks screen opens.

      2. Tap the Wi-Fi switch on.

      The screen expands to give you the option to Choose a Network, as seen in Figure 2-5. iPhone detects servers in the area, and the Wi-Fi symbol indicates how strong the signal is: the more waves, the stronger the signal. Servers that require a password have a closed lock icon next to them.

      

Some Wi-Fi networks may require you to agree to the provider’s terms before you can use the network. In those cases, a prompt appears, asking for your permission to launch Safari to view the provider’s web page, where you typically tap a check box indicating you agree to the legal mumbo jumbo listed on the web page. In other cases, you have to type in a username and password in order to agree to the provider’s terms.
