Actually, I believe it really is 'unlimited,' as they're assuming you're not tethering and only using the phone to do your browsing. If you get a data card, or a tethering plan, then you'll see that limit imposed. There are scores of people who use their Pre's to listen to Pandora all day, and regularly go over 5 gb/month and never have a problem. Might that change in the future? Yes, but so far it's not a problem.

Not to mention the fact that any MBA program worth it's salt will require 3-7 years of work experience before they'll admit you.

Just get the bits out of whatever you're trying to archive and chisel the ones and zeros into stone tablets. In 25 years, dig them up, run some OCR on them and reconvert them into electrical bits rather than rock bits.
