In that last generation of TouchFLO 3D, the internet tab allowed you to add Push Internet pages which would preload certain favorites at a specified interval. It seems that this feature didn’t get much use because it’s being phased out for the next version of TouchFLO 3D to show up on the HD2.
As show below, you can add a grid of favorites to the new Internet Tab. What’s neat is that you’ll also get a mini preview of the content of the webpage (similar in function to the iPhone). Then, you can place any of your favorites (with the mini preview) on your Home tab, giving you one-touch access to your favorite site.
