here's mine with Push Notifications On(Only Facebook), Location Services On (Maps, GPS Drive, & Find My iPhone), 20% Brightness. oh, last but the least...i'm jailbroken.
I've checked facebook, twittelator, & tumblr a bunch of times, watch like 5 something videos (YouTube & Vimeo), surf a forum on Safari, tethered for a couple of minutes, and couple 2 minute calls, and a bunch of text messages. all in intervals of switching from 3G to WiFi.
