I wasn't even sure if the CDMA Verizon version had 4G capabilities or not, but my 3GS is starting to really show it's age (and perhaps is getting clunky as a result of its internal memory being used a bit?), and after witnessing some friends with Sprint showing off their 4G I was pretty jealous/impressed (and heck, from what I am being told that's not even true 4g).
