You do not know anything about legallity if you think it is not illegal...seriously, kids.

If Apple would have activated that feature, it would not be illegal.. but as they blocked that feature, it is because they are licenses about it... you break the lock, you break the license.

When you buy a phone, you also agree to not break this feature... so if you do, your phone is not supported anymore... bring me the documentation from Apple that say the opposite before telling that this is legal.

Suggestions like this are making the market unstable, because newbies will do it, thinking it is legal... remember that you can be sued if you break your license and suggest others to do the same.

@Paul M... this action is illegal the same way the nullified vBulletin releases are... exact same situation.
