Let the hive mind of Engadget get that for you.
"As someone who doesn't reside in the USA, I was wondering what would be the best way to get internet for my computer in the US for a couple of weeks? If it were Europe I know I'd look for some prepaid data. Is there anything similar offered by American carriers? A MiFi or a data SIM that I can tether from would work, but I'm trying to maintain a tight budget. Help!"

I would also add that most of that info is IN the viewfinder, so when your looking through the camera, you can already see that.. the screen is to view it, when your NOT looking through the viewfinder, like you said.
