Should large numbers of workers buy up LTE-ready iPhone 5's to use on the job, their impact could generate greater corporate costs to cover expensive data plans from wireless carriers. That's especially true for smaller companies subject to data-sharing plans implemented by Verizon Wireless and AT&T, analysts warned.

A big lure of LTE comes from the ease of sharing photos and video more quickly and easily on the job, analysts said. More images than ever can be sent out unauthorized and, therefore, pose a security risk to enterprises, one analyst predicted.

"Given the weakness of Research in Motion and BlackBerry, the iPhone 5 wave could move a massive number of workers over a short period to a new, relatively unsecure device, resulting in security breaches," warned Rob Enderle, an analyst at Enderle Group, in an email interview. "Greater picture sharing with a new generation of users suggests unauthorized pictures will be shared of unannounced products, bad executive behavior, and confidential events that find their way out of the company far more frequently."

If a company is paying for workers' data plans, or sharing those costs, he added, "companies may find their charges go up sharply before their employees get benefits." That's because LTE networks don't yet have widespread coverage nationwide and data plans are "very expensive," Enderle said.
