name@me.com and MobileMe accounts

[naftalim]

For some reason, I have the following accounts listed on my iPhone

myname@me.com (Contacts, Calendars)
myname@me.com (Mail)

MobileMe (Contacts, Calendars)
MobileMe (Mail)

When I send an email to myname@me.com it appears in myname@me.com and in the MobileMe account as well.

I'm confused, should there be both of this or only the MobileMe?
