RIM has repeatedly claimed it lacks the ability to directly decode its encrypted BlackBerry e-mail and messaging services.
India first threatened to ban BlackBerry services in August unless RIM enabled state surveillance of encrypted email and IM conversations, citing concerns the services could be used to organize terror attacks with impunity.
The home ministry gave RIM until August 31 until services were shut down, but this deadline was lifted after RIM provided a technical solution.
If the system implemented by Indian operators fails to satisfy intelligence agencies, RIM will have until the end of January to come up with an alternative or the ban will be enforced.
