What does the message mean? I use a POP3 account and when I get an email one day it has the preview message on the screen and when I press it, it gives me the full message. Later in the day or the next day when I go to read the same message there is no preview and when I press it to read the email I get a loading icon then the message, "message not downloaded from server," even though I read it the day before. Why doesn't this 8gb ipod store simple text email? Is it a POP3 issue or and iphone issue? It has been hard going from a Blackberry email system to this. C.
