Will this bumper work for the Verizon iPhone 4? http://store.apple.com/us/product/MC672ZM/B?fnode=MTY1NDA0NA&fs=m.iphoneCompatibility%3Diphone4%26m.tsFormFactor%3Dbumper It states on their website that it fits all iPhone 4 models, but I just wanted to make sure. Also, I thought Apple had a deal where we could get 1 free bumper because of the signal issues, is that still possible? If so, how do I get it? Thanks!
