Description in the Site:

What's a jailbreak? Why jailbreak?
A jailbreak is simply the ability to run apps and use themes and tweaks not approved by Apple. Jailbreaking doesn't slow down your device or use any extra battery, and is fully reversible (just restore in iTunes). A jailbreak lets your device be how you want it.

Is JailbreakMe reversible?
Of course! If you ever decide that you want to remove your jailbreak, just connect your device to your computer, sync, and then press Restore in iTunes.

Is this legal in the US?
Yes. A new DMCA excemption was approved by the Library of Congress, specifically allowing jailbreaking.
