Have not used it much but the initial impression looks good what with 3g working, responsiveness is lot more smoother and even am able to download from market without problem... Try this out if you are interested (Thanks for whoever posted Ist here in slatedroid:D)
EDIT: Played 1080/720 HD videos with mxvideo player and they are buttery smooth. Havent tried youtube, so cant comment on that as I hardly ever use it!
