All this talk about 3G/4G speeds, hotspot, etc.... I was thinking just how much time everyone spends away from a WiFi connection they can use? My normal day consists of getting up, going to work, and coming home. I spend maybe 2-2.5 hours away from the house while driving to/from work, picking/dropping off kids, going to the grocery store, etc... So usually when I want to access something on my phone, I will be around a WiFi signal I can use (Home or Office). I would think with WiFi on the EVO, thats where most of my data usage is going to be. When using android apps, they use WiFi (if available) correct?
