Not sure what the 'don't/can't use' is about. Works great, even with more than one gmail account! ^_^.

You do have to hit the "Home" Button to Start. But, given that there are Back, Forward, Refresh, Open in Full, Settings, and Information Buttons (all with Classic, well-know images), it isn't hard at all to work.

You have to log in, but that's just like regular Gmail. This uses Gmail Mobile View, so you still have the menu, Gmail's Refresh, Compose, & Search Buttons.

Easy as Cake (which I like better than pie!).
