I am sure we had a very similar question asked already, but I cannot find it.
Anyway, there are internet plans by network carriers that give you "free facebook megabytes", which means you can browse facebook at no cost, but cannot see outside resources. For any other websites you gotta pay.
So this got me wondering, how could one bypass this by maybe using facebook as a proxy, as you can do with the google translate? how does the carrier know you are browsing facebook, obviously not by IP because there are too many, and by domain? there are a lot of those too, but they all probably point to .com anyway...
So I dunno... thoughts?
