Among others, there will be the following two fall outs because of the SC case in 2G scam:

The incumbent operators will benefit

An immediate fall out of the Supreme Court judgement will be that the incumbent operators like Bharti Airtel, Reliance, BSNL etc. will benefit since the 7 crore  and odd subscribers of the companies whose licences have been cancelled would like to change their connections to the other operators. It is not much difficult now with the number portability as they can keep their original numbers.

Tariffs my go up

There is every reason that the tariffs may go up, especially because  of the new development connected with the reduction of profits due to  stiff competition. Bharti Airtel and Reliance have already decided to hike up the tariff. Other companies including BSNL are expected to follow suit.
