I check my gmail account regularly through the Mail application on my iPod touch. I have it set up with IMAP. Previously when I hit the trash icon the message would get put in my "all mail" folder and removed from my inbox. The last couple days the message is going straight to the trash. How do I get it to archive messages again? I've tried to select "all mail" in the settings for deleted messages, but it always reverts back to trash.
