Really? I am under the impression that they have four databases: 1)
crippled (gpl) country db, 2) non-crippled (commercial) country db, 3)
crippled city db, 4) non-crippled city db.

We would use #1, and I'm not sure how that compares in accuracy to #2.
I believe both #1 and #2 are bad at telling you whether an IP address is
located in, say, Tunisia -- after all, Maxmind's customers generally get
no revenue from Tunisia so they don't care whether it's accurate there.

And it's an open question whether #2 is any better than #1 at answering
questions about Tunisia.
