Okay, here is the situation: Until now I have been using Gmail Pop through mail.app. I never access my email through the gmail website. Gmail archives all of my messages on the website as soon as they are downloaded, so my inbox online is always empty. I organize all of my emails into folders in mail.app and not with tags on the gmail website. I have an iPhone now and would like to use IMAP to keep things consistent. How do I go about doing this so I don't lose all of the email organization that I have in mail.app? What is the best way to go about this. Will IMAP push those POP folders back or what? I don't want to have to re-organize thousands of messages. Essentially, I would just like to start using IMAP from this point onward, keeping what I have now. I don't want to mess anything up either. Thanks so much for your help.
