Despite the perception that BlackBerry still rules in corporate smartphone circles, Apple says that 93 percent of Fortune 500 companies are testing or deploying the iPhone. Last week’s announcement of the iPhone 4S should inspire even more businesses to take a hard look at handing out the devices to mobile workers, Aaron Freimark, IT director at services firm Tekserve, told CIO.com. Here’s his thinking. It Avoids the 4G Façade: 4G chipsets drain battery life and LTE coverage is spotty. As of now, many perceive 4G as more of a marketing gimmick than a technological breakthrough. Busy executives should be happy with the new phone’s eight hours of 3G talk time and 10 hours of video. It has Good Data Transfer Speed: Apple says that the iPhone 4S running on 3G networks including HSPA doubles the iPhone 4 download speed to 14.4 Mbps and uploads at 5.8 Mbps. That’s good for business users who download big reports and business-relevant podcasts and video. It has a Built-In Assistant: The early buzz on Siri, the voice-activated personal assistant, is good. What businessperson wouldn’t want another assistant, even if it’s only to check flight times or the weather in Chicago? It’s Global: For the first time, the iPhone is a world phone, with unified CDMA and GSM. That’s one phone for business trips to Tulsa or Tokyo. It has Airplay for Presentations: Airplay, or wireless mirroring to the iPhone, connects to Apple TV. That means you can carry an iPhone, an Apple TV (which is tiny), and connect via HDMI to a screen at your destination to run a presentation off your iPhone. Slick. Source: CIO.com
