OK I've seen it mentioned here that after getting the update some people's version reads 2.1 and others read 2.1 Update 1. Anyone know what the difference is? My daughter has a Sprint Samsung Moment that runs the Android OS, she was on 1.6 and was having poor battery life. She went to the store and they told here to remove some apps and stop back another day and they would update her OS. She went back yesterday and they updated it for her, took them 1/2 hour. Now she has 2.1 Update 1.
