From Android Central:
File this under "unofficial" for now, but we're getting word on dates for Sprint to update the
Samsung Moment, which at current is still running Android 1.5. And even better is that the update reportedly may be Android 2.1, and not merely 2.0
as Sprint told us earlier.
The first wave is said to begin Feb. 22, and you'll have to visit a Sprint store to actually get the upgrade. A pain, yeah. But it also keeps you close to home should anything untoward happen.
The second upgrade wave is said to be on March 8, and that one will be pushed out over-the-air.
Thanks, anon.
