RIM said consumers would have to wait for devices running its next-generation BlackBerry 10 software because the integration of a huge volume of code into the platform had “proven to be more time consuming than anticipated.”
Until recently it had maintained that the long-awaited new phones would be available to purchase in late 2012, in time for the crucial Christmas buying period.
Last night RIM said losses for the three months to June were $192m (£123m) as revenues plummeted by 33 per cent to $2.8bn.
The firm also said its plans to cut 5,000 jobs – about 30 per cent of its workforce – as it looks to reduce costs in the face of falling sales.
Shares in RIM dropped 15 per cent to $7.75 in after-hours trading on New York’s Nasdaq.
