When viewing a blog view for a category of articles in the iphone view of Mobile Joomla, the published date was not showing up in the articles. The created date would appear if it was turned on but the Published date just showed a heading.
It appears to have been a bug in the code.
Edit /templates/mobile_iphone/html/com_content/category/blog_item.php
Locate the following line (around line 58)
<div class="published"><?php echo JText::sprintf('COM_CONTENT_PUBLISHED_DATE', JHtml::_('date',$this->item->publish_up, JText::_('DATE_FORMAT_LC2'))); ?></div>
Change it to
<div class="published"><?php echo JText::sprintf('COM_CONTENT_PUBLISHED_DATE_ON', JHtml::_('date',$this->item->publish_up, JText::_('DATE_FORMAT_LC2'))); ?></div>
