Why?
Apple’s smartphone comes locked with particular carriers. Across the world, Apple sells its flagship phone only through carriers. It is often a headache for an owner, who wants to enjoy the freedom of using any SIM or any data plan in his/her handset. Every version of the handset including the 3GS comes with the disturbing restriction.
It is a process of tailoring the device’s firmware to make it compatible to any carrier. You may have bought your phone from AT&T or Verizon. But, after you modify its firmware you can operate it using any SIM card – both domestic and international. The major advantage of the activity is that you can reduce your data bills as well roaming charges.
Going overseas, you will have to rely on the foreign partner of your device’s default carrier for using data and making calls. Indeed, it is a pricier deal. After you customize the device, you can slot in any SIM card and thus save some valuable bucks during the stay abroad. Further, when it is in homeland, you can enjoy multiple and affordable data plans on any network with a SIM change.
This is why it is largely practiced among the Apple phone users across the world. It is not an illegal activity, anyhow. Even if Apple is against it, there is no illegality in it. The U.S. Copyright Office has legalized it on the base of ‘fair use’ terms. So you can do your own modifications and enjoy seamless freedom. Visit: Why
