Problem with a telephone model

Hi everyone!
I'm a student and I'm learning to use solidworks (2 months of course)
For a university project I have to recreate with solidworks a phone (Panasonic - KX-TG6712) .

The problem is that when I model the phone shell with the 'loft' function, I can not recreate the curved parts at the ends of the phone.

Can anybody help me with this problem?

It's probably a very simple exercise, but I'm spending several days trying to find a solution!
