I currently have three email accounts which I have setup by just going into the mail settings and selecting gmail, not sure if that's IMAP or POP. To be honest, I'm not even sure what the difference is between IMAP or POP. I primarily use gmail and have labels setup so I would like to be able to move emails to various folders/labels. I'm just curious how you guys recommend setting up my email and if it's better to select the gmail option or using IMAP by following the guide that Google has for iPhone users. Also, here is one problem I'm having. When I setup my email and go into mail.app I have the inboxes options which has the unified inbox as well as all my other email accounts under it. Then there is the Accounts tab. When I added an exchange account is showed up in the account section of mail.app but whenever I got an email I'd receive it twice, and it got really annoying. And I'm not sure what the difference is between going to the accounts section of mail.app as it seems that I have all the options that I do under the inboxes option (the first group of emails you see when you launch mail on the iPhone). I'd really appreciate some clarification in this matter. Thanks in advance.
