    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 especially appreciate how easy it is to delete messages and clear the trash bin, something Android's standard mail app couldn't do.

    Rápido, pratico, interface limpa. O único que gerencia mais de 1000 emails.

    The client would be awesome if it actually pushed email accounts

    ...and by far the fastest client I've found for previewing lots of consecutive messages. Best of the best! Keep up the good work guys.
