Engadget claims to have heard from an inside source that the handset is next in line for the platform holder's latest operating system.
The Nexus S was originally earmarked for the software in December following the release of flagship Android 4.0 handset the Samsung Galaxy Nexus, but Google halted its global rollout to monitor feedback.
HTC and Samsung previously confirmed that their flagship handsets will receive Ice Cream Sandwich over the coming weeks. Sony's Xpera range will also be given the update.
Android 4.0 Ice Cream Sandwich is the first Google OS to run on both smartphones and tablets. The software launched with the Galaxy Nexus in November last year and is expected to become a dominant force in 2012.
Elsewhere, Google is rumored to be working on a Nexus Tablet to rival Apple's new iPad.
