What is the difference between overnight and expediated shipping?

I need to know because my dad bought me an iphone and he chose a expedited shipping and my phone will come around Sept.25 to Oct. 2.

Overnight is overnight and very expensive. Expedited can mean many things to each company. Usually is just means it will be first in line to be shipped normally. Or it can mean nothing if he didn't pay more for the service.

Usually products don't ship over (like late 11pm to 1, 2, 3 etc am the next morning) but with the overnight option they do.

Expedited shipping means it would get there faster than it would normally. Of course this costs more.

Expedited shipping might refer to express or priority shipping, as both are faster than the customary first-class mail process. Overnight shipping refers to the shipping that may take overnight time period.
