30 MB wouldn't even work for me if it was per day.
Unlimited is supposed to mean unlimited. If they limit you to 30 or 120mb, even 3 gb it's
limited... obviously. I don't understand how they come up with calling it unlimited. That's BS. It's false advertising and it's underhanded at best. 30MB is total crap.
I've used 7 gb in a month once with Cingular. That wasn't even with my
N95... if they charged me a dime more than my unlimited data plan was, it'd end up coming out of their pocket.
