It's possible to create href-attibutes that makes the iPhone quit Safari and launch another app. For the official Twitter-app this would look like:
<a href="twitter:///post?message=my+important+message">Click to deliver message to Twitter-apps status updater</a>
For the Facebook-app the protocoll is:
fb:///
But i can't figure out, or find any information about, how to get my message (a url to share) directly into the the status updater.
Is there a url-scheme, or am I going about this the wrong way?
