Using a mobile phone as a modem isn't a new feature
— in fact, many smartphones came and went before the iPhone had this
capability.
Tethering means you don't need a
Wi-Fi hotspot or a separate mobile broadband modem to access the
Internet on your notebook or PC. Your mobile phone or smartphone becomes
the modem and uses your network's 3G data service to connect to the
Internet.
Apple's launch of the 3.0 iPhone
software in June last year brought tethering to the attention of a
broader audience than previously. It used to be used mainly by corporate
road warriors, but the decreasing cost of 3G data and the increasingly
popularity of smartphones mean that tethering is now more appealing for
students, office workers and travellers.
An
iPhone can be used as a tethered modem when physically connected to a
computer with a USB cable or wirelessly connected via Bluetooth. Follow
our step-by-step guide to find out how:
1. Update your software
Before
attempting to tether your iPhone, you should ensure you've updated to
the latest iPhone software, as well as the latest carrier software.
Simply plug your iPhone into your computer, open iTunes and click the
"check for updates" button when the iPhone screen appears.
