Hacking

I have been looking into this subject recently and am still trying to fit this topic into this paper. I want to talk about hacking, and more specifically talk about hacking the iPod touch and the iPhone. Ever since the two came out there has been different organizations trying to exploit the iPod touch's programming in order to copy the iPhone's menu. They have succeeded in doing this and there has been arguments on this subject, is it right to hack the iPod touch or not. Also some of the same organizations have hacked the iPhone making it available of T-Mobile customers, too when Cingular had paid for specific rights to the iPhone. I want to talk in depth on the subject of hacking in whole and about this current debit on the iPhone and the iPod touch, is it ok or not?
