People are excited about new US Government rules that say that unlocking and jailbreaking the iPhone or any other cellphone is now legal. I'm happy about it, but it really doesn't matter much to you or me. Here is why.
Unlocking allows you to make a cellphone work with any wireless provider you want, freeing you from abusing policies like insane international roaming charges. Jailbreaking lets you install any application you want, even if it has Apple-censored content or provides with tethering, all without having to go through the iTunes App Store or pay Apple a single cent.
