It's .6 and just don't do it. Talked to Samsung Tech support and it adds nothing off value while causing battery drain and browser issues as noted in this forum. They are aware of the problems and working on a fix.
You know I had little to no problems with the update. The first day my battery dropped horribly. I then cleared the ram and did a battery pull and ever since then I've had no issues. That fact that the update fixed the AP mobile bug was enough for me to stick with it.
