I'd say that a necessary part of being a hacker includes considering the purpose and importance of things that you're hacking on. Hack on your hobby Raspberry Pi or the side project you're working on at home to your heart's content. Don't hack around on the production servers for your multi-million dollar business.
The phone that you use to organize your real-life events, keep in touch with the people in your life, get important alerts, etc. is more towards the production server level of importance than the toy gadget. I recommend thinking twice before putting some hacked-up barely-supported ROM on it.
I feel the complete opposite: the phone I use everyday and has become more important in my digital life than my pc, must be hacked (owned) by me even more.
Hacking means making it work to your needs, despite all the limitations some clever suits have decided on your behalf.
For example my phone carries some immigrant files and I need them stored as files, therefore I am not able to use non hacked Apple devices.
