Anyone that is interested in this topic knows how frustrating it was when the original iPhone did not allow for connecting to wireless networks using 802.1x for security. A lot of businesses and universities use this to secure their wireless networks and so a lot of people were out of luck and had to connect to the Internet via the cell network even though there was a fast Wi-Fi connection available.

Well, they've added 802.1x to the iPhone but it isn't accessible from the phone itself. Instead, they have a special application and guide for use by Enterprise users that you can download from the Apple website:

http://www.apple.com/support/iphone/enterprise/

You actually create a new Configuration Profile in that application, adjust all of the settings (TLS, TTLS, PEAP, LEAP, PAP, CHAP, etc.), choose the type of security (WPA, WPA2 Enterprise, etc.), add the certificate (if necessary) to the credentials tab and set the trust settings, and then email the configuration to whichever iPhone you want to configure. When you click on the attachment in your email (on the iPhone) it asks if you want to install the profile. It takes a couple of seconds to install and then you are on the network. All in all it was pretty simple and it was probably faster to setup from within this utility than it would have been on the iPhone. Also, if you are the one deploying these to end users you can easily create one profile and email it to all of your iPhone users at once.
