In yet another blow to beleaguered Canadian tech giant Research In Motion, the US government's Immigration and Customs Enforcement (ICE) agency has filed to stop using BlackBerrys for its agency smartphones, and will instead switch to Apple's iPhones. The deal, worth $2.1 million annually, will provide iPhones for most of the agency's more than 17,600 employees, according to a solicitation document obtained by Reuters. ICE studied both Android and iOS as options before deciding that iPhones best met its needs.
