1. So I own a iPhone 4s from sprint, will the Aluminum e13ctron s4v case for Verizon (CDMA) iphone 4 & iPhone 4s fits my sprint 4s? 2. I am planing to get a matte top & polished bottom. Will this mix works? If so am I suppose to buy every parts Separately? 3. Is there any difference between the replacement liner kit: inner plastic case liners versus the original clear one??
