Samsung Media Hub beta available now, only for AT&T Samsung Galaxy S II
Purchased content can be viewed instantly while it is being downloaded over Wi-Fi. Using the cloud, any purchased shows or movies can be viewed on up to 5 devices and can be viewed an unlimited number of times until the expiration date. Once you decide to participate in the beta test, Samsung will send you a $25 gift certificate that you can use toward purchasing movies or television shows on the Media Hub. After the testing is over, you will receive a survey to fill out which will let the Korean based manufacturer know of any problems with the software.
