My company provides free wifi throughout our building via an account system, i.e. when you connect to the wifi you are re-directed to a login website into which you put your personal details and it then allows you to access the rest of the web. They also provide a profile for mobile devices such as iPhones; when you set up your device with this system it automatically connects you to the network without the need for your login details each time. Obviously, the mobile profile version is the preferred method of access as you don't have to re-enter your password each time you wake your phone from standby. The only problem with this method is that, recently, they updated the profile to alter your iPhone settings to enable the passcode lock, so basically if you want to use this other network, you have to unlock your iPhone with a passcode every time you wake it from standby. This blows. I've emailed the IT department regarding this but they said the passcode system is mandatory because it protects users from unauthorised web access through their mobile devices. Which I think is a bit heavy-handed; if someone else gets ahold of my iPhone, whether or not they browse the web from it is likely to be the least of my worries. Does anybody know if there's a way to edit the profile to disable the mandatory lock screen settings?
