3G, or third generation, is the generic term used for the next generation of mobile communications systems. The new systems will enhance the services available today and offer multimedia and internet access and the ability to view video footage.
With a 3G phone and access to the 3G network you can send and receive video calls, watch live TV, access the internet, receive emails and download music tracks, as well as the usual voice call and messaging services found on a mobile phone.
3G technology gives iPhone fast access to the Internet and email over cellular networks around the world. iPhone 3G also makes it possible to do more in more places: Surf the web, download email, get directions, and watch video — even while you’re on a call.
