Regardless of the reason, the Copyright office said that it is not illegal to jailbreak an iPhone - but that help if you screw something up and you want Apple to fix it under the warranty. You Breaky, You Fixy....
- Copyright Office says jailbreaking your iPhone no longer violates copyright law
- If users want software not in the App Store, they need to jailbreak their phone
- BTW, it's already legal to unlock your used iPhone for use with another mobile carrier
