In general, almost any device with a radio will indeed need regulatory approval before it can operate commercially. Amateur GSM projects *have* obtained temporary approval for testing purposes in the past, though.
However, claims that modified GSM firmware can lead to interference with cell operation and emergency service represent either fearmongering or exactly the kind of problems that this project intends to expose and potentially fix. If those problems exist, they exist *already*, so wouldn't you rather know more about your GSM firmware and GSM's limitations rather than less?

In emergency situations GSM networks can restrict access to ordinary subscribers - I think some of this access control is handled in the phone in order to make sure that bandwidth is preserved for high priority users.
