      There are many ways to upgrade to 5.1.1 version.If you enter your phone into DFU mode and restore and update it to latest version,you can have many choices to jailbreak it.

      Enter your phone into DFU mode (by holding power and home button for 10 seconds and then holding home button for 10 seconds),while keeping it connected to iTunes and then it'll restore it.Then update it.
