Tweet links (URLs) from an iPhone to Twitter
tweetymail allows you to easily tweet links from your iPhone without ever leaving Safari. It's a quick, two-step process. To start, let's say that you are viewing a web page and want to tweet a link to the page...
Step One - Choose to mail the link
Tap the "+" at the bottom of Safari and select "Mail Link to this Page".
Step Two - Fill out the email and send
Enter firstname.lastname@example.org in the "To:" field and you are ready to send! Notice that the subject is automatically filled in with the title of the page. If necessary, you can modify the subject or add text to the body of the email before sending. tweetymail will automatically shorten the URL for you.
Best of all, sending the email takes you right back to Safari :-)
