Android 2.4 is actually Ice Cream Sandwich, possibly a version of Honeycomb for phones
An interesting theory about Android 2.4 has been put forth by IntoMobile. The idea here is that Ice Cream Sandwich will be a version of Honeycomb for phones. Andy Rubin has stated that Honeycomb would be meant for tablets but be compatible for both tablets and smartphones. With the smaller sized screens on a phone, the Honeycomb OS might not produce images that would work on say, a 4.3 inch screen as opposed to a tablet sized display. So the thinking goes that Android 2.4 takes a little Honeycomb, mixes in some of its own features and adds up to Ice Cream Sandwich. Of course, all of these theories just might be getting way ahead of things. After all, Android 2.3 has yet to be downloaded to all appropriate Android handsets that meet the system requirements which means no Ice Cream Sandwich until you finish your Gingerbread.
