Prepare to mash the System Update button, A100 owners: the promised update to Android 4.0 (Ice Cream Sandwich, or ICS) has apparently been rolling out since yesterday. Word came to us last night from Canadian reader Graham, who provided a handy-dandy picture as proof:

An XDA thread confirms Graham's update wasn't a fluke, with users all around the world receiving the update. So far the thread is 10 pages long but contains little by way of comments on the user experience after the update, but it does look like the ICS update is preceeded by a smaller 17MB update. Other than that, we have little by way of details at the moment.

Update: You can get build 1.014.00 right here, which is the same as the OTA.
