Can my phone provider legally upgrade my phone OS without my consent?
<p>I wonder whether my phone provider can legally upgrade my phone's operating system without my consent.</p>

<p>I am most interested in the United States, especially California and Massachusetts.</p>

<p>No, they can't legally update it without your consent.  </p>

<p>(This includes consent in the form of a document you agreed to such as usage documents by AT&amp;T, as well as the stuff Google has you accept before you use their property (like the Android OS, for example).)</p>

<p>You entered into a license with the phone OS provider when you started using the phone. They can do whatever it says.</p>
