For anyone wondering when the beta will start, it should drop sometime during the first week of September. It will likely start in South Korea and then the US a couple days later. Just regularly check for the banner at the top of the Samsung members app to join once it is available in your country/region.
I haven't heard anything other than the official announcement that it will be this month. Depending on your carrier it could be even later. Verizon is notorious for not letting customers participate because it supposedly voids the warranty.
I know China got it Wednesday I don't know about other countries but I have T-Mobile so I'll be able to get it I've been checking a few times today but I haven't heard anything about it.
Yeah, since I use Verizon it is still up in the air as to whether I will get to participate or not. But it will be interesting to see how samsung decides to roll it out to the public.
