Business users meet gatecrashers at UK iPhone launch

The story was different for many of those who worked for larger corporations. One example was Richard Innes, who works in finance in the City.

Currently a BlackBerry user, Innes said he doubted he would be allowed to use his iPhone in a business setting. "It's a big corporate network," he said. "If I was in the media, I could easily use the iPhone, but I don't think I could use it in a corporate environment."

O2 has warned that many procurement departments may not allow employees to transfer their work numbers to an iPhone because it is only available on a consumer tariff. The security implications of the device's use in a corporate setting have also not yet been established.
