This one isn't quite completely official just yet, but a helpful tipster has passed along the screenshot above which quite clearly suggests that some software updates are coming to a trio of Sprint's Samsung devices on March 21st. That includes a new and hopefully improved over-the-air upgrade to Android 2.2.1 for the Epic 4G, as well as an Android 2.2 update for the Transform, both of which also include a number of other additions like Flash 10.1 on the Epic and Swype on the Transform. Also not left out of the fun is Sprint's version of the Galaxy Tab, which is getting the Sprint ID update we saw first hand at CES back in January -- it's headed to the Epic and Transform as well.
