I read that the edges on the side of the front glass were sharp. Are they? Even the slightest rough edge will annoy me so yeah would be good to know. Also, how good is the loud speaker, for ringtones and speakerphone? I'm getting sick of these very bad loudspeakers on my last three Samsung smartphones, pining for the days of Nokia stereo speakers on chunky bar phones. Doesn't need to be loud, just has to sound very good and not hurt my ears when it rings, like the way my Infuse does right now.
