pretty sure i have the same case as you do.
here is what i do
squeeze the sides of the top part of the case
then press on the logo, right under the seam in the middle of the phone
you should then be able to slide it out.
the phone will NOT come out just pulling it with brute force, but i find it EXTREMELY easy using the method above. but i got my phone and case used, so maybe it was "broken in" before I got it
