updating a device without cellular contract to froyo2.2
<p>Since I already have a mobile phone (and contract), I bought a <strong>droid X</strong> <em>without a contract</em> so I could write apps for it.</p>

<p>I am confused about how to update this device to 2.2 Froyo so I can get started with developing.  Is there a guide or guidelines for the upgrade/installation process?  It looks like the <a href="http://android.git.kernel.org/" rel="nofollow">code is here</a>, but I need help understanding how to move it from git to device.</p>

<p>Thank you!  (FWIW, <a href="http://stackoverflow.com/questions/468722/developing-for-a-windows-mobile-phone-without-a-contract">this question</a> is very similar to mine... but for windows mobile)</p>
