I'm anxiously awaiting the wider rollout of EV-DO Rev A by Sprint. It'll be nice to upgrade from my current Rev 0 card and actually have useful upstream bandwidth...
It is nice seeing 3G GSM services finally being rolled out in a decent fashion though. It'll be even nicer when I can get proper HSDPA/HSUPA service from T-Mobile since I refuse to deal with other US carriers for voice, having been through almost all of them at one point or another.
