I know I am not happy with T-Mobile. What I don't understand is we get the beta from Samsung and it works on our phones so why can't we get the final from them too. Doesn't pay to beta test. Although heard T-Mobile is releasing or released the final on the 15th of Jan.
I think the best option for beta testers is getting them the final release. Just like beta if it doesn't work you can go back. We have been on beta and if it's working then there shouldn't be a problem with the final. Carrier can then send out their updates to it later. Leave the option to the users and not the carriers.
