What is 3G?

By

Definition:

3G is the wireless network standard used in the iPhone 3G. It is called 3G because it is the third generation of cellular telecom standards.

3G is a faster network for phone and data transmission than EDGE, which was used in the original iPhone:

EDGE: 1 Mbit/s download and 400 kbit/s upload
3G: 14.4 Mbit/s down and 5.8 Mbit/s up.

3G’s ability to handle more data makes it faster, but also improves the phone call sound quality.

Support for 3G in the iPhone 3G is generally seen as a factor that contributes to faster drain of the phone’s battery.
