iPhone Push

How many ways are there to put themes on an iPhone?

My sister just got an iPhone and asked me how to put different themes, since I am a tech MAJOR. Geek, and she mentioned the term "prison guard." As I am familiar with the prison guard and before the process very easy (iTouch is done), it does not ruin his phone. I told him to use the iPhone Configuration Utility to back everything up, but it has no idea of what it is and it does not lose his phone. I was wondering if there is another process by means of putting a theme on an iPhone without Prison forefront. If yes, please name!

No, the phone must be jailbroken. A new operating system comes out. Depending on the phone, it has, there may be no solution to jailbreak it. I suggest you go to Modmyi and read between the posts.
