Gmail updates for iOS

If the next Gmail message you receive on your iPhone launches YouTube or Google Maps, don't be alarmed. The Internet giant enhanced its official Gmail app for iPhone and iPad today, adding two small but appreciated features for heavy users of the Web-based mail service.
First, the default behavior for opening YouTube, Google Maps, or Web links has changed. Now, when you click on any of those kinds of links, Gmail will spawn the respective native YouTube, Google Maps, or Google Chrome app for iOS to handle it. Formerly, such links were instead handled by the relatively inelegant built-in Gmail browser.
If you don't want those links to spawn their native apps, i.e. you prefer the old default behavior, click into the Gmail menu using the button marked with the three horizontal bars, and then click the configurations button with the gear icon. At the bottom of the preferences screen, click the large button labeled "Google Apps." You'll be presented with the option of turning off Chrome, Google Maps, or YouTube links.
