Maybe a big family? I dunno. Anyway, yeah, my step from 3G -> 4 is pure win as well. No problems whatsoever. I've already recorded a video of my twins and uploaded it to YouTube (definitely bummed about not being able to upload HD vid over wiFi though, and I still have to get used to iMovie for editing). I love this phone more than any other iPhone from Apple so far, even more than the original (which I also LOVED).
