Please, and I can't emphasize this enough, PLEASE read all instructions and research before rooting. If you are not technically adept, I don't recommend this at all. I am seeing a lot of cases of people rooting and flashing ROM's without even knowing how to go to system settings to see what version of the radio they are currently running.
THIS IS A RECIPE FOR DISASTER! Please research things THOROUGHLY and make sure you understand all aspect of rooting before doing anything. Otherwise, you will run a strong risk of bricking your phone and costing yourself a lot of money.
