IPhone :: Cannot Sync Email On It?

After many hours searching the net and these forums I still can't find the right answer to my question.I have an email account with Go daddy (I beleive it is a POP account type). I use this email for business purposes and receive many different emails everyday, therefore using folders with my email account is crucial.This is not a problem on my mac as I have plenty of folders created, however I cannot sync them onto my iphone, therefore whenever I want to find a message on my iphone I have to search through tons of emails before I reach the correct one.I understand that there are certain apps that can facilitate email folders such as emailganizer and web outlook app, however as im sure you are aware they do not accept pop email accounts! Is there any way of me creating folders on my iphone somehow using my pop email account? Is there any way of me keeping the email account name, (mike@personaltrainingforhealth.com) and the web hosting with go daddy but changing the email provider so that I can use one of the apps available that allow you to create folders
