Nerval's Lobster writes: "The National Transportation Safety Board (NTSB) plans on replacing its existing stock of BlackBerry devices with Apple’s iPhone 5. Research In Motion’s BlackBerry smartphones, the government entity wrote in a Nov. 13 notice of intent, “have been failing both at inopportune times and at an unacceptable rate.” The NTSB’s use of iPads means it has the operational support for iOS; consequently, the decision was made to go with Apple. “The iPhone 5 has been determined to be the only device that meets the dual requirement of availability from the existing wireless vendor and is currently supportable by existing staff resources,” the notice added. RIM is fighting to retain the government and enterprise contracts that originally made it such a mobile powerhouse. If agencies and boards such as the NTSB begin to embrace alternative platforms, however, that could critically weaken RIM’s business model just as the company attempts a comeback behind the upcoming BlackBerry 10 platform."
