Mid-Atlantic. This is what everyone calls a Philadelphia accent although it's also the accent of south Jersey, Baltimore, and Wilmington. Well, everyone that lives near there, that is. Outsiders can tell you talk differently from them even though they can't tell what your accent is.
Northeastern. You're probably from somewhere near New York City, possibly north Jersey, or Connecticut or Rhode Island. If you are from New York City you may be one of the types who people never believe when you say you're from New York.
