Same issue, absolutely cannot feel it in my pocket when on silent. Not sure if it is the new materials that mask it or whether it is vibrating less but either way, I'm missing calls.
ash =o)
haha, but on a serious note, i've missed several calls with my iphone4 because I didn't notice the vibration. is it just my phone or others notice the vibration is weaker than the 3g/3gs?
