I have the pink and black faded ihome case on my iphone 5 and it is stuck?

I need to get this case off soon. It's supposed to be one of those cases where the bottom comes off then you slide the phone out but the bottom won't come off. I can't use a knife so please don't suggest that. Do you think I should take it to the apple store? That would be my last choice but if I have to I will.

Just carefully use a dull butter knife.pop out with some force.
