sorry if this has been asked before, i searched and could not find an answer. im running gmail push through exchange server. basically, im wondering if there's a way to get my older emails from my gmail account to show up on my ipod. currently only new emails that have been pushed from gmail show up in my inbox, and after i read them, they disappear. i cant read them again unless i log into my gmail account from my PC. any way to fix this?
