iPhone 4 icons

[Flower aught 2]

Is it possible to change the ICON pictures on an iPhone 4 without getting into the "jailbreak" or hacking of the phones files?

It is not possible unless you gain access the the file system.

Does this void the warranty.

No. It's not possible without jailbreaking. I wouldn't worry about voiding the warranty. You simply restore the phone and remove the jailbreak if you ever have to take it in for replacement or repair.
