Heard the iphone 4/5 will have a screen almost as big as the HTC, mainly because the HTC's screen is so big, it looks like a wallet in your pocket. And that it'll have 4g enabled, and instead of a glass back, a carbon back.
These are just rumors, but it sounds good to me.
I've seen an artist's render of it, lemme dig it up.
And 4.3 inches of metal feels pretty good in your hand, it's not too huge.
