3G and 4G???

Most cell phones use 3G but carriers and now offering 4G. But the thing is: what is the difference? Well first 3G and 4G are ways to communicate and transfer data especially for the Internet. Most phones today use 3G. With techniology advancing, more cellphone can use 4G. What makes 4GH better than 3G is it can transfer data faster than 3G. Another difference is that 3G uses circuit and packet switching.4G uses only packet switching. Today, carriers are now offering 4G like Verizon AT&T, and Sprint. But does 4G work on these carriers? Carriers do have it but a lot of people cant use it because of what they are located, so they still have to use 3G. Today people still use 3G and in the future more people will be able to use 4G.
