Big news from Posterous today: a iPhone version of their posts. They have taken the time to alter the view when bringing up a Posterous site on your iPhone. Not only the views, but also the upload mechanism so photos and videos are resized for the iPhone screen size.
iPhone users can swipe left and right to go back and forth between pages! On a blog list page, swiping goes to the next and previous list of blog entries. On a blog post page, swiping goes to the next and previous blog post.
This is great timing as we are seeing more and more folks posting to Posterous since it is so simple to get started sharing.
