    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.

    Would open too many connections to gmail. No easy way to limit the number of connections it opens. Would frequently get errors when getting emails on other devices due to k9mail opening so many connections.

    5 stars when it works. 1 star if it doesn't work at all. It works great 50% of the time..certificate errors the rest of the time.
