It looks like owners of Acer's Iconia Tab A200 have something to celebrate today, as reports of an update (to Android 4.0.3) began rolling in early this morning. The update brings the A200's build number up to Acer_AV041_A200_1.037.00_PA_CUS1.
If the update hasn't hit your A200 just yet, you can check manually using the ever-familiar process: just go to Settings > About tablet > System update > Check now. It's worth mentioning that this build is different from the version that leaked several days ago (1.019.00), but there's no word yet on exactly what the differences are.
