for the most part they are the same. except for a few things: rings and vibrates at the same time custom short cuts ascending ringers for 2 secs not 7 theres now a red skin instead of tmobile one pix on the camera are used as full wall papers so that you don't have to take a pix in 240x320.
and there are a few more. some mite say its not worth the time to do. i belive it was. its the little things that count. i love being able to hear and feel my ringer. i haven't missed a call since i updated. hope this helps
I bought a "Samsung D820" from eBay source in the USA because I wanted to use the answering machine function of the D820 in a country in Africa. Unfortunately the one I have do not have the answering machine function although the manual I downloaded says it has. Any advise is highly appreciated (softawre,etc..).
