Android 4.0 Ice Cream Sandwich and its flagship smartphone, the Samsung Galaxy Nexus, will be released in November, but consumers are anticipating an operating system update for older Android phones.

The Nexus S is the first smartphone expected to receive an Ice Cream Sandwich operating system update. The Samsung Galaxy S2, the Motorola Droid Razr and Droid Bionic may receive updates in the future.

All of the phones currently run on Android 2.3 Gingerbread.

Google representatives said any Gingerbread powered phone has the potential to run Ice Cream Sandwich, however, it has been confirmed that the HTC Nexus One is too old to receive an update.

Google's Product Management Director for Android Hugo Barra announced on Oct. 26 that the 1 GHz Scorpion processor that powers the Nexus One is too slow to run Ice Cream Sandwich.

Barra, as well as several other sources, have confirmed that the Nexus S will receive an Ice Cream Sandwich update "in a matter of weeks."
