I just said why the heck not and tried DroidVPN without any beforehand configurations on CM7.
And it works!
When I tested it without DroidVPN, by opening up XDA and going to a couple of topics it billed me a couple of cents, with it it didn't bill me anything!
Also I saw this:
Account Type: Beta Tester (Premium accounts will be available soon)
Does that mean that you will have to pay to keep using it, or will there be free and premium accounts?
EDIT: Never mind, I guess the data on my carrier's website takes some time to upload.
