According to one of TmoNews’ sources, we should already be seeing select users of the T-Mobile G1 and myTouch 3G getting OS update notifications for the Donut based Android 1.6 build.
If you have gotten the update, let us know in the comments below!
Update: It’s official. I just got word from T-Mobile’s PR firm.
“The rollout of Android 1.6 (Donut) to T-Mobile’s G1 and myTouch 3G customers is now underway. The over-the-air update will be delivered to all G1 and myTouch customers in the coming days.”
