Sprint announced about a month ago that they would be updating their Android phones (HTC Hero and Samsung Moment) to Android 2.1 sometime in the first half of 2010. We have yet to receive any details on the exact rollout, but it appears things are going well. The update is already in testing according to a post on the official Sprint forums.
A while back we announced our plans to update our Android devices to 2.1 in the first half of 2010. I just wanted to follow up with a quick status. The 2.1 update is currently being tested and things are going very well so far. We’re still targeting the first half of 2010 and if things continue to go smoothly we should have the update well within that time frame. I’m sure there will be a lot of questions about procedures and more exact time-frames but for now I won’t be able to say much more. I just wanted you all to know that things are still on track.Sprint Employee
It still remains unclear exactly how Sprint will update all of these phones. They initially told us no OTA updates for Android phones, but the Hero did receive a minor update wirelessly. That was followed by a Samsung Moment update that was sent out the old fashioned way (drive your phone to a repair center).
