For me the Otterbox Impact cases are just perfect. I have a few in different colours that I can easilly switch on my 4. They are good protection and I love how they cover the home button. But I see they didn't make an Impact series for the 5. Is their anything similar from a quality brand? I'm debating whether to replace the battery in my otherwise fine 4 or upgrade to the soon to be released 5S and sell my 4.
