The iPhone features an integrated Web browser, tiltable 7.4-inch gray scale touchscreen, an e-mail client, a 56-kilobits-per-second modem, two phone jacks, a full duplex speaker phone, and a keyboard that slides under the phone to save space.
Setting up a wireless network in the home requires at least two components: a wireless hub, which connects to the modem (DSL or cable) or server PC, and a client device such as a PC insert card, which connects to the hub.
