Users love the iPhone, but IT does not. The biggest complaints: The iPhone can't be managed for security and access policies like a BlackBerry can. Businesses can buy a BlackBerry Enterprise Server or Motorola Good for Enterprise server to manage user profiles over the air, ensuring that users conform to password policies, encryption policies, app-installation restrictions, and so on, as well as have their e-mail, VPN, and other settings preconfigured to reduce hands-on deployment effort.
