Jailbreaking Your iPhone

Jailbreaking your iPhone allows you to eliminate the restrictions imposed on tailoring your cell phone to your specifications by your software. It is important that this be done properly and carefully so that no damage is done to the software causing the phone to malfunction.  

Though this is a possible risk it is not a common one.  What this process achieves is liberation of sorts.  You can add customized options such as ring tones and wallpapers which are generally restricted on the phones.  Considering the cost of the cell phone itself, you should be able to personalize the phone the way you want.
