Adding New Folders in Email - Comcast Account

I have been reading IMAP messages for over a day and am trying to figure out something.

I use comcast mail system. It appears to me that I can not use IMAP for their server. Only POP server type. If that is so does that mean I can not create personal folders for my email account on my iphone? I have Inbox, Trash, Draft, Sent but no option to add a personal folder. I would like to save off messages to personal folders and move them out of my Inbox.

I am new to posting questions on this site so if someone already answered this, I'm sorry about that. Thanks
