I want to update my iphone 4s without Wi-Fi?

I want to update my iphone on pocket inter net

Sorry, but you must have Wi-Fi to update. It is because the phone must maintain a connection to the Internet to install and the carrier's data is inaccessible before the software is installed

Justin got it twisted. Update it using iTunes on a pc. Plug up, click, and go. Best luck.
