How it works.



iPhone 3G uses a technology protocol called HSDPA (High-Speed Downlink Packet Access) to download data fast over UMTS (Universal Mobile Telecommunications System) networks. Email attachments and web pages load twice as fast on 3G networks as on 2G EDGE networks.1 And since iPhone 3G seamlessly switches between EDGE, faster 3G, and even faster Wi-Fi, you always get the best speeds possible.

Talk and browse. At the same time.



iPhone already gives you mobile multitasking. But 3G technology lets you multitask in more places — without connecting via Wi-Fi. Since 3G networks enable simultaneous data and voice, you can talk on the phone while surfing the web, checking email, or using Maps. All from your 3G cellular network.

Go anywhere.



iPhone 3G meets worldwide standards for cellular communications, so you can make calls and surf the web from practically anywhere on the planet. And if you’re in an area without a 3G network, iPhone connects you via GSM for calls and EDGE for data.

More wireless. Less space.



iPhone 3G delivers UMTS, HSDPA, GSM, Wi-Fi, EDGE, GPS, and Bluetooth 2.0 + EDR in one compact device — using only two antennas. Clever iPhone engineering integrates those antennas into a few unexpected places: the metal ring around the camera, the audio jack, the metal screen bezel, and the iPhone circuitry itself. And intelligent iPhone power management technology gives you up to 5 hours of talk time over 3G networks.2 That’s some of the best in the business.



1. Testing conducted by Apple in May and June 2008 using preproduction 3G/EDGE-capable iPhone units and software and currently shipping EDGE-capable iPhone units and software. Testing was conducted by browsing to www and measured uncached page load performance. All settings were default except: Call Forwarding was turned on; the Wi-Fi feature Ask to Join Networks and Auto-Brightness were turned off. Wi-Fi was enabled but not associated with a network. Throughput depends on the cellular network, location, signal strength, 3G/EDGE connectivity, feature configuration, usage, the Internet, and many other factors. Throughput tests are conducted using specific iPhone units; actual results may vary.

2. Battery claims are dependent on network configuration and many other factors; actual results may vary.
