Every year, data usage grows on the internet by more than 2.5 times. Most of that has to do with streaming video, and your service provider (for home internet and cell phone service) may soon be charging you more.

AT&T, notorious for it's poor infrastructure (which is plans to fix by buying T-Mobile), has had caps on the amount of internet data you can send and transmit with your cell phone for over a year. It's one of the reasons many savvy consumers choose unlocked cell phones, such as "jailbroken" iPhones, so that they can switch networks when monthly prices go up.

And the need to have unlocked cell phones may go up; more carriers are expected to begin putting data caps on internet cell phone use. Smart phone users, beware, if you aren't choosing unlocked cell phones, you may get stuck without internet, charged more.

How do unlocked cell phones help? You can use your favorite phone on any network; unlocked cell phones are broken of the restrictions carriers place to limit how you use the phone. (The market leading iPhone is the best example of why people love unlocked cell phones: until Verizon picks it up, AT&T has a monopoly over it, unless it's a unlocked cell phone!).

Want to save money? Then buy unlocked cell phones now, and if, as expected, Sprint and other networks add data caps, you can vote with your subscription and change carriers with unlocked cell phones!
