Android 4 Ice Cream Sandwich

Ice Cream Sandwich was Google's attempt to synthesize Honeycomb, it's tablet-only platform, with its mobile platform. Released in October 2011, it features a new design and default font, as well as the ability to monitor and limit mobile data usage and other upgrades. Many devices were slow to adopt Ice Cream Sandwich. Three months after Ice Cream Sandwich, only one phone (Samsung Galaxy Nexus) was released to run it.

In real life, an ice cream sandwich is a layer of ice cream, usually vanilla, sandwiched between two cookies, usually chocolate. They are often rectangular in shape.
