This decision is  result of the efforts since the 2008 proposed.

Whatever the decision is now allowed to pass? Although written in legal language enough to make the forehead wrinkled, the following conclusions:

1. Mobile phone users can do a ‘jailbreak‘ to install the application, legally acquired, on their mobile phones. Although the application was not officially allowed by mobile phone vendors.

2. Mobile phone users can do a ‘jailbreak’ to access the wireless network operators that they want, as long as it was allowed access to a network (such as a customer service person).

3. DVD owners should turn off the anti-piracy protections on DVDs to take a piece of picture that will be used by non-commercial use, eg for education, criticism, comments and so forth.
