One of the best things about Android is the constant OS updates. It has had about 5 major OS upgrades since its original launch. One of the worst things about using an Android phone is not knowing when your manufacturer will update your phone with the latest Android OS version.
Motorola seems to have understood this problem that many Android users have and has released a schedule of Android software upgrades for Motorola phones. It includes a list of all the major Android phones by Motorola (including the Droid X, Droid, Cliq, Devour, Backflip, Milestone and the Dext) with a list of countries and a timeline.
