What can I do with my old iPhone
<p>I currently use my iPhone 3G for testing my apps, but I am thinking about upgrading to the iPhone 4.  What can I do to my 3G so I can still use it for testing.  I don't need it to have 3G access, I just want to be able to put apps on it for performance testing since it is a slower device.  I would still like to keep Wi-Fi access if possible.  What options do I have?</p>
