Consumers in the US and Canada have sued Research in Motion for a three-day service outage on BlackBerry devices that rippled across the world earlier this month.

The US lawsuit, filed on Wednesday in the federal court in Santa Ana, California, was brought on behalf of all US BlackBerry owners with an active service agreement at the time of the email, internet and messaging interruptions.


It accuses RIM of breach of contract, negligence and unjust enrichment.
