As you probably know by now, versions of the Android OS tend to be alphabetically named and include some sort of reference to a dessert. Therefore, it was only reasonable to assume that the version of Android following Honeycomb would be called "Ice Cream."
However, according to Andy Rubin, that is not the case - instead, the name will be "Ice Cream Sandwich."
We still don't know Ice Cream Sandwich's version number, the features it will introduce, or anything else about it, but for those of you interested in the reason behind the name, TechCrunch has a pretty good theory: Google's statue for Android 2.2 includes frozen yogurt, which would be pretty hard to distinguish from ice cream. Therefore, tacking "sandwich" onto the end of the name will enable them to create a statue for this version of Android without having it look virtually identical to Froyo's sculpture.
Whatever the case is, one thing's for sure: we can't wait to see it!
