The just-released Mailplane 2.1.6 from Uncomplex adds built-in support for the highly interesting Rapportive plug-in (see "Rapportive Plug-in Replaces Gmail Ads with Sender Info," 27 March 2010). Mailplane 2.1.6 also now works with the Share > Send via Mail menu items in the iWork '09 applications. With them, you can email your document via Mailplane in its native format or as a Word, Excel, PowerPoint, or PDF document. A few minor bugs have also been fixed, some of which were related to Gmail changes. ($24.95 new, free update, 6.7 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.
