Google may be planning to keep Android 2 and 3 segregated in a long-term split of the platform, according to a ViewSonic source on Monday. The 2.4 update, once thought to be called Ice Cream, is now said to be a continuation of Android 2.3 (Gingerbread) that would simply add backwards compatibility for dual-core apps on single-core phones. Ice Cream, Pocket-lint heard, should be Android 3.1 and would keep the two apart in features and the interface.
