Maybe you've seen the ads from Verizon Wireless: flashes of red lighting, booming thunder. It's not the end of the world, it's 4G for phones.
But what is 4G? And, more important, is it worth the price?
Faster service? Maybe. 3G and 4G refer to third- and fourth-generation wireless networks, respectively. However, the "G" service applies to data only. Faster speeds refer to how quickly data such as apps, photos and videos can be downloaded from the Internet to your phone or other wireless device and vice versa.
How much faster? No one seems to agree.
