Sharing multiple images over e-mail works like this in PR 1.1.1.:

* Open "Images"
* Drop down the additional options from top bar of screen
* Choose "Share (images)"

The app now allows you to choose as many images as you like. When you're done, press "Share" on the top bar. You will now be prompted to share the pics via Bluetooth, a service like FB orl by e-mail.

This is how I've done it so far.

EDIT: Oh, and integrated FB chat has been in as well for a long time. I would bet that it was in since day #1, as I remember being fustrated about it because I had though MSN would be native, not silly FB.
