I have my Macbook connected to the Internet via a mobile USB modem. &nbsp;I'd like to share this connection with my iPhone. &nbsp;I tried this <a href="http://forums.macrumors.com/showthread.php?t=281234" rel="ugc">http://forums.macrumors.com/showthread.php?t=281234</a>&nbsp;but don't see the Macbook from the iPhone when I try to join a network. &nbsp;I'm using OS X 10.6.3. &nbsp;<br />
<br />
In the sharing section, I have &quot;Share your connection from&quot; set to Airport. &nbsp;The only option under &quot;To computers using&quot; is Ethernet. &nbsp;However, I do want to share from the Macbook wirelessly. &nbsp;Any suggestions how I can get this going?<br />

Also, where are the encryption options as mentioned in the article.
