The current range includes the BlackBerry Torch 9850, Torch 9810 and Bold 9900, each of which debuted back in August. Newer phones may address user frustration with BlackBerry – the survey found just 14-percent of enterprise users questioned were happy with their devices, versus 44-percent of those with iPhones – but neither hardware nor RIM's Enterprise Server software can save businesses from the sort of downtime experienced last week. That outage spoiled a 99.97-percent uptime record built up over the past 18 months, co-CEO Mike Lazaridis pointed out in a post-mortem conference call, but embarrassingly coincided with Apple's iOS 5 release and the launch of iMessage, a rival to BlackBerry Messenger. Whether RIM's sales-speak statement will be sufficient to win back the trust of enterprise users – along with the month of free technical support they've been offered as partial compensation for the outage – is questionable.
