RIM's four-day BlackBerry outage might have cost it $100 million, JPMorgan Chase analyst Rod Hall estimated on Friday. Although he couldn't verify exact pricing because of RIM's confidentiality, he based the estimate on the calculation that RIM would collect $1 billion as part of its usual revenue sharing with carriers. Hall cautioned that there could be a significant margin of error, but he added that RIM would have to likely have to pay at least some of it back.
