About 4G Technology

The next installment in network technology is 4G, which will improve Internet speed, and incorporate better programming. This is still new technology, and only a few mobile phones are equipped with it so far. With 4G technology, mobile phones have the ability to be slimmer, and the IP will enable video/audio streaming. This means that video blogging will be possible with the new iPhone 4G. The extension from 3G technology will provide a wider spectrum for Internet usage anywhere in the world.
