I'm anticipating my iPhone arriving next week... I have a question about how email is handled, specifically as it relates to storage space I'm going to be setting up my gmail (IMAP) and university (POP) emails on the iPhone. Both of those accounts are also set up in Mail.app on my Mac. I'm concerned about the storage space my emails will take up. Will all my thousands of emails actually be stored on the iPhone? They would take up a couple gigs on their own... Is it possible to 'unload' emails off the iPhone so they don't take up space, while keeping them on my Mac and the web servers? Basically how do you manage having thousands of emails on a small-capacity device (that you also want to use for other things, like music)?
