Finally, Epic 4G users on Sprint will get the FroYo update starting from December 26. According to a leaked screenshot, the Android 2.2.1 update will be pushed over the air, not the usual Samsung Kies way as in the case with other Galaxy S phones.
Unless, something goes wrong in a big way, we are expecting update to hit this time.
Find more details in the leaked screenshot below.

Sorry but it is not going to happen, it was delayed once again, maybe in Jan 2011.
