The Financial Times is reporting that "someone" - some US regulator - is "interested" in the mobile advertising provisions in Apple's iOS SDK. Apparently while they know this, they don't seem to know which regulator cares nor which if any is going to do anything about it.

I'm no lawyer, but by all (sane) accounts Apple is pretty much in the clear. They don't have a monopoly position which to abuse. They don't forbid third-party ads nor ad networks. They only block parties with clear conflicts of interest from spying and stealing their IP.
