This tool is used in enterprises to setup multiple iPhones. Settings include device security policies, VPN configuration information, Wi-Fi settings, APN settings, Exchange account settings, mail settings, and certificates.
Enable tethering
To use tethering without having to enable it on your subscription, go to http://help.benm.at/help.php on the iPhone and use the 'Create mobileconfig' link in the middle of the page to create a new .mobileconfig containing the APN and username/password. Search Google to find the APN for your operator.
Once the mobileconfig is created, the iPhone will ask to install the unsigned file. Tap install and wait for it to install. Check System preferences to see if it's possible to enable tethering. To add MMS, go to Network, Cellular Data Network and input the MMS settings.
