It looks like users that have been lucky enough to get the bump to Android 4.0.3 (which, by the way, does not include the new Galaxy Nexus just yet) are also finding a couple of new options in Gmail. The new options are under the heading of "Experiments" in the settings menu.
There are only two options available, but they both sound pretty cool. They actually seem to be features that Google probably would have wanted to have ready for the launch of Ice Cream Sandwich, but somehow missed the deadline. The first option will allow Gmail to index entire messages to improve local search. The other will allow users to drag and drop contact chips between the To, CC, and BCC address fields.
As yet, only the Asus Transformer Prime and Motorola XOOM have the official update to Android 4.0.3, so the new features may be limited to those devices. However, if any of our readers have a custom ROM built on 4.0.3, or a Nexus S running 4.0.3, we'd love to know if the "Experiments" tab is there as well.
