The Android 4.0 rollout for the GSM/UMTS Nexus S has begun, according to a post to the official Google Nexus Twitter account. A corresponding help page has been set up over at Google’s support page to aid Nexus S owners in the transition to the latest version of Android. The rollout starts today and will continue to reach Nexus S owners throughout the month, though for the impatient we expect an official update file to surface online for those wishing to manually upgrade.
