An iphone is "locked" to a network, in the sense that it can use no other network other than the one that it is programmed to. The U.S. iphones are locked to AT&T, U.K. iphones to O2 and EU countries to T-mobile; the iphones brought in these countries can only connect to their respective networks. Therefore if you travel to another country or over seas you will be charged heavy roaming prices and you may also not be able to take advantage of various schemes in other networks. Unlocking or jail breaking comes in handy here, once an iphone is unlocked it can connect to any other network. Thus you can make calls at cheap rates and save a lot on the roaming tariffs.
Iphone unlock is an organisation providing softwares for unlocking iphones. They provide reliable and easy to use software that can be installed quickly within five minutes. This software helps you make use of a number of facilities and decreases your call rates. Another advantage of jail breaking is the installation of Cydia and installer applications that helps you download hundreds of games, ringtones, tools and other applications all for free. It is like breaking down the fences and venturing into open space.
As this discovery is gaining ground a number of companies have entered the market offering free unlocking software, however these free products could cause more harm than good. A cheap or free software could disable some applications for good or at the worst spoil your iphone completely. An expensive device like that cannot be afforded to be spoilt and hence it's important to find out about the company before trying out the software. Apple does not support jail breaking of it's devices and as such you cannot hope to get any assistance from them in case of an unlocking mishap'. Even most phone insurance companies do not cover unlocking.
Iphone unlock provides safe software which has been tried by customers and appreciated. It comes for a one time payment which also includes life time membership and updates. A 30 day guarantee is another safety backup incase you are not satisfied.
