Quite maddeningly, my LG GT540 insists on deleting any eMails more than four days old. To make it worse, there's not an option to save a message, or create a folder. I can move individual messages, but only to the pre-made Sent, Drafts, Outbox folders etc. I can't find any settings to fix this; the receive messages settings section has an option to download messages from the last 3 days, 10 days, 30 days etc. but I can't find anything about keeping messages. It's infuriating... (Running Android 1.6).
