Depending on which country you bought your iPhone 4, chances are that it is locked with contract from a single service provider. While there is no harm in having a contract with your iPhone, but chances are you will be limited by the provision of the contract. If you can buy an IBM or Mac computer and have the freedom to choose your internet service provider, then it is only fair that you can buy an iPhone 4 and choose the phone network you would like to subscribe to. That is why iPhone unlocking or jail breaking is 100% legal.
To unlock iPhone 4 is to disable its internal restrictions that prevent owners from using SIM cards from other networks. Even after unlocking your smart phone you are still able to use the original SIM contract that came with the iPhone 4. Limitations that come by when you visit a foreign country are also overcomed since in some countries the SIM automatically picks the carrier company that Apple entered into trade agreements with and so sometimes you are left with no choice but to operate with a provider that charges you more compared to other providers.
Other than the obvious reasons of having the choice of changing your provider at any time if you have your iPhone unlocked, there many other benefits. Bottom line is you can just do a lot more with your smart phone when its unlocked or jailbreak. You can jailbreak and unlock any model and version of iPhone successfully without tampering with the internal functions of the phone. Because of the high costs of the iPhone, most consumers believe they are actually getting their phone at a cheaper price, but come to think of it in the long run you actually get to pay more whether you get to use your phone or not you will still have to pay some money on the contract every month.
