Doing this really doesn't require the network info API, you can generally figure this out by using a public database to look at the client IP. There are databases which do IP to GeoLocation, and I'm pretty sure you can find databases that will tell you which connection class an IP is on.

It also doesn't lead to a good UE. If a user has unlimited or employer paid service, then being told that a "large" file is problematic is just annoying. Especially if every file they access is "large". If my plan gives me 20GB, then being warned about "20MB" files is maddening.
