Unlocking the 4S Nowadays, in the cellular phone marketplace, there are more options for smart phones that a single person could fathom. Unless of course you work for a cell phone company/store that offers multiple different carriers, over several different platforms, that for the most part cannot be interchanged. At the pinnacle of this subject is the highly valued iPhone. Which at one point in time, was only offered through one carrier AT&T. But because of the extremely high demand for the phone, slowly but surely other carriers opened their gates to supporting the iPhone and its highly sophisticated software and application market. Even after the other top cell phone carriers (Verizon, Sprint, and even some prepaid plans such as Boost Mobile) have allowed the induction of the iPhone to their option plans, once you purchase the phone from a carrier there are certain things that you become “locked” into that the carrier you choose is not going to let you in on. Basically, when you purchase a phone from a carrier the phone is then “locked” in with that specific company. So in able to receive a monthly service plan from them you have to abide by their guidelines and pay for certain aspects of the service. Regardless of your usage (you can see my site for more info). The company basically has a leash around your neck and whatever changes they decide to implement, in order to maintain service, you must pay for them. The carriers put this into affect to keep people from purchasing iPhones from one company and then they decide to switch to another carrier while still under contract and use the same phone. It keeps the new company from losing out on any revenue that would be generated from the sale of a new phone when switching to them. (see iUnlock 4s for more info) On top of having your phone locked in with your carrier when you purchase an iPhone, you are also locked in with the Apple Corporation itself. Apple puts these measures into place because in the company's eyes your phone, that you purchased for hundreds and hundreds of dollars, is only a module which they allow you tom “borrow” and use their technology on. It makes it so regardless of the carrier you still must follow Apple's rules and regulations as it pertains to the technology they are loaning to you. With these parameters put into place it would seem that you really don't have much of a leeway when buying an iPhone, even if purchased from Apple. It would seem once you dedicate yourself to a carrier you are stuck with them and even if you wanted to change, you couldn't. However, there are numerous programs now available to consumers that allow you to unlock your phone and lift the restrictions put on by the carrier and the Apple Corporation. When you unlock your phone it allows you to use your phone with other carriers that use different SIM cards, not just the company that you signed your contract with. This gives you the freedom to shop around and find a carrier that fits the needs your looking for and the price point that fits your budget for monthly service. Just make sure that the carrier's servers your looking to work with support the software of the iPhone before you make the switch.
