Bug on iPhone/safari for iOS

Having received a couple of comments in my blog recently (really excited about that, at least someone is reading a couple of my articles ) I therefore tried to reply to those posts with my blogger app for iPhone but nothing happened. In safari for iOS I disabled the block pop ups but nothing changed. Anyone else have this problem? My friend Peter told me he tried to comment on a post from his iPhone but couldn't. Let me know if you have this problem. In the meanwhile I'm gonna try and look into it.
