In the United States, jailbreaking smartphones is legal under exemptions to the Digital Millennium Copyright Act (DMCA). These exemptions are reviewed every three years by the Library of Congress. As of 2025, jailbreaking smartphones remains legal for personal use. In the U.S., network unlocking is explicitly legal under the "Unlocking Consumer Choice and Wireless Competition Act" signed into law in 2014. This law makes it legal for consumers to unlock their phones without carrier permission, though carriers may still set their own policies regarding when they will provide unlocking. This comprehensive guide aims to empower you with the knowledge and tools to take full control of your mobile device through two powerful methods: jailbreaking (or rooting) and network unlocking. Why This Guide ExistsThe mobile technology landscape is constantly evolving, with new devices, operating systems, and security measures being introduced regularly. What worked for unlocking or jailbreaking a phone in 2023 may no longer be effective in 2025. This guide provides up-to-date information on the latest methods, tools, and considerations for freeing your device from manufacturer and carrier restrictions.
