I've heard in the past many discussions about this, especially with the iPhone and jailbreaking. People modify the phone software to allow them to do things the software either doesn't do, or prevents for some reason. Now, personally, I believe you should be able to modify this software as much as you want, with a disclaimer that says "Once you do this, bye bye warranty and any type of decent support." I think bricking the phone is completely unacceptable.

But on the devil's advocate side of me, things are different. You bought the hardware. It is your legal property (unless you are leasing it. Read your contracts people). You can modify it, solder it, paint it, whatever you want. That's perfectly fine because you own it. But when you jailbreak something, you are actually modifying the software. This is a different story. You license software. You don't own it. It's not treated as a tangible thing you can own. It's similar to owning a book. You own the paper, the ink, but not the words on the page. With a book you have to respect (respect meaning abide by, not necessarily admire) the copyright, but with software you have to respect license. If you dont like the license terms, then don't use that software. If Motorola's Android flavor has something in it you don't like, roll your own Android flavor and install it over. While that doesn't seem practical, that's the way it works.

Personally, I don't see any harm in modifying the phone operating system software to get it to do what you want, as long as it is for personal use. No harm to others, no foul. Break your own phone, well, that's your problem. But from the standpoint of software is licensed, not purchased, I understand. It's like an author not wanting someone to rewrite the ending to their book.

To sum it all up, if you root/jailbreak your phone or in other ways violate the license/EULA for your personal use, it's "wrong", not wrong.
