    The only thing that bothers me about this app is that every time I change the notification settings to silent and uncheck vibrate, for some reason they go back to the original notification settings. This is so annoying I'm thinking about uninstalling.

    This works great with my LG Ally. If I send a picture with regular GMail, it takes forever or maybe not at all. With K9, it is immediate.

    My archive, move and spam buttons are grayed out How do I make them active? Other than that this is an awsome app.

    I'm using this app since my first android mobile and I loved it. With the latest release it happened twice to read a message and the attached document and then loose it: the read message cannot be find any more. I'm seriously considering to stop with this app! Very disappointed!
