Uncomplex's Mailplane 2.1.9 offers the capability to drag .webloc and .mailloc files into Mailplane to insert the URL encapsulated in the file into the message text. But the real reason to upgrade to Mailplane 2.1.9 is the fix to the problem that attaching files via drag-and-drop often didn't work if you had also upgraded to the recently released Flash 10.1 (which you want to do, since the previous version is a security hole; see "Adobe Flash Player 10.1.53.64 Blocks 32 Security Holes," 11 June 2010). The update also fixes a problem dragging text clippings to Mailplane, fixes a focus problem caused by upgrading to Safari 5, and improves performance when composing replies. Release notes are available. ($24.95 new, free update, 7.7 MB)
Type an em-dash on an iPhone
Typography and punctuation geeks rejoice! It's easy to type an em-dash on the iPhone's or iPod touch's virtual keyboard. To do so, tap the .?123 key to switch to the numeric keypad. Then touch and hold on the Hyphen key to reveal a pop-up strip showing an em-dash. Slide to the em-dash and release your finger.
Note that this basic trick works with many other keys on the virtual keyboard.
