I know it's all in my head, but I'm wondering if its happened to someone else. My old iPhone was broken, so i popped into my reseller, and got it replaced. This new one is a tiny bit different. Of course is the exact same model and such, but the following things feel different: 1. It just feels softer. 2. The vibrations aren't as vibratey. 3. The sound on/off switch is clickier... This may be because my old one was just broken in. Anyone else have the same feelings?
