Does iPhone OS 3.0.1 ruin your development phone?
<p>I updated my phone to 3.0.1.  While the phone works fine as a phone, <a href="http://en.wikipedia.org/wiki/Xcode" rel="nofollow">xcode</a> organizer no longer knows the name of the phone.  It also says 3.0.1 is unsupported by this version of xcode.</p>

<p>I downloaded the latest version of xcode and OS (3.1).  Now, I'm trying to move my phone from 3.0.1 to 3.1.  I'm pressing option-restore in <a href="http://en.wikipedia.org/wiki/ITunes" rel="nofollow">iTunes</a> (does this bring in the beta OS?).  It tells me all the data on my phone will be erased.</p>

<p>How should I proceed?</p>
