The Guardian reports that the launch of BBC News and BBC Sport smartphone applications is to be delayed, after the BBC Trust heeded industry calls for it to review the corporation’s apps proposals. The BBC had been planning to launch its BBC News app next month and a BBC Sport app in May, both of which would be compatible with the iPhone (with future launches planned on BlackBerry and Android-powered devices). There are also plans for an iPlayer app. The BBC unveiled its initial app plans at the GSMA Mobile World Congress in Barcelona last month.
