Finally have a new version of Netflix app(1.3) released today that works on the Best Buy S7 version 104. This is the first version of the Netflix app that works!
I was able to get netflix 1.4 to work on my stock bestbuy brand S7. I just got it back from huawei it had 2.2.1 on it. I just pulled the APK file from my phone
[APP][Updated 9/13/11 V1.4] Official Netflix - xda-developers First page is updated with the newest version. I downloaded the apk, and it works on S7-104 (rooted, but stock 2.2.2). Once launched, netflix asks for you to update in the market, but the update is unsupported. But no need... it works fine with just the apk.
