I have installed the bumper optimized BestSkinsEver skin (front + back but no side) on my iPhone 4. I'm looking to complement it with a bumper to provide some fall protection without making the phone too bulky. Tried the Apple bumper first and it was terrible. Way too loose on the sides. Other issue is that I need to use my Shure SE315 earbuds with the iPhone while the bumper is on. The jack for these earbuds is ENORMOUS; did not realize this when I got them as a Christmas present. I'm thinking a thick rubber/silicone type bumper is best, since I will likely have to enlarge the headphone jack hole using a knife. What bumper alternatives are out there which could potentially fit my needs? edit: I see I screwed up the title and cannot change it. Wonderful.
