I have a 2-piece phone case. I popped the top part off but the bottom won't come off. I try to force it off with my hands, but it's too hard. I use tweezers and pencils and things to dig under to snap it off, but it won't budge. It's on a slide keyboard phone, and I've tried slidin my phone but it's still staying on. Any ways to get it off? I lost my insturctions paper thing, so I have no clue how to get it off And I don't mind breaking it. Thanks (:
