Controls and Connectivity – iPhone 3G
Consistent with Apple’s design philosophy for the iPhone, user control of the iPhone 3G was conducted exclusively through a large multi-touch screen and a single button on its face. Up front, the display was dominated by a single mechanical Home button below it that doubled as the main navigation key. The volume rocker for quick audio adjustments was on the left side, accompanied by a ring/silent switch for silencing alerts. A power/lock button sat up top, as well, joined by a 3.5mm headphone jack for the old-crowd-standard wired earphones (and which supported inline controls on compatible headsets).

It was a huge step up fro its predecessor in terms of connectivity, bringing 3G UMTS/HSDPA support for faster mobile internet. It also delivered quad-band GSM/EDGE for the use around the world. Wireless was Wi-Fi (802.11b/g) and Bluetooth 2.0 + EDR for use with accessories. The two devices differed only in the bottom where Apple included their 30-pin dock for charging, syncing with iTunes, and connecting to a host of peripherals.
Although it was missing things like NFC and LTE — the iPhone 3G offered a variety of connectivity options so it could still be used as a phone, messaging device, music player and internet communicator with simple, easy-to-use controls.
