So, I was looking into buying a Otterbox Armor series from eBay, but I noticed that they only made them for the iPhone 2G. I currently own the 3GS, so I was hesitant. I haven't bought it yet, so I was wondering if you thing the old armor series would be compatible with iPhone 3G/3GS?? Anybody own the Armor?? Please help! Thank you so much!
