I went from a D1, to a D2, to a DX to a DX2 and after that one took a swim, got the Bionic 4 days ago, even though I planned on waiting for some other 4g phones...best decision in my Droid purchases x10. The phone blows the DX2 out of the water (literally). Not only does slingbox stream on 4g with ease, but is perfect with 3g as well. In Fact, I can stream HD off my cable box component in HQ Quality on Slingbox with Bionic...this was never possible with DX2...kept breaking up, so the difference between apps on 3g between the DX2 and Bionic are night and day...tested 4 different streaming apps and got the same result on all 4. Even started using the ZumoCast which is factory installed and it streams movies with no buffer issues from my Mac Mini at my home over 3g.
As I stated, I've had 5 Droids and this is the ONLY one which operates at the speed one would want with absolutely NO force closes on any apps in 4 days.
I simply re=downloaded the app from market on Bionic and worked fine...initially, I transferred the apk from DX to DX2 during the time slingbox wasn't available on market and that worked as well, and that apk was emailed to me from a friend...no I'm not rooted on any of the phones.
