From th BBC: Blackberry spurns Indian spy call
"The Canadian manufacturer of Blackberry mobile phones has rejected demands by the Indian government that it help decrypt suspicious text messages.
Research in Motion says its technology does not allow any third party - even the company itself - to read information sent over its network.
The Indian authorities have been reluctant to allow the widespread use of Blackberries in the country.
They fear militants and criminals may take advantage of the secure system.
A number of other countries around the world have expressed similar fears. "
