IT Business Edge contributor Ralph DeFrangesco seems a bit nervous when it comes to iPhone security.

"With the convergence of voice, video and data, users will store on these devices documents including contact information, personal documents, and e-mail, and that's just to start. What about the users that are storing client lists, personal information, IP data, and work e-mail on them? This device has a big red bulls-eye on it that says, 'hack me and I'll bleed information.'"

DeFrangesco is not alone. Many businesses are nervous about deploying the iPhone because of bugs and glitches. DeFrangesco urges companies to treat the device like they would a company PC.

"There should be a development and test environment where the business, support, infrastructure, application staff, and security professionals can test applications thoroughly to understand their impact on the device and the data, before the end user gets the application."

iPhones in the workplace have become more prevalent and two resources in the Knowledge Network look at security issues and more.
