Surely if you can figure out a way to do it, Apple can't stop you, which is a different argument to whether Apple makes it easy for you to do?That is not technically true because if you owned the physical device then you would be allowed to do with it what you will. The fact is you cannot because Apple does not allow other OS from being installed on an iphone or ipad. If you actually owned the physical device then you should be allowed to install an OS from Microsoft, Blackberry, Google, Linux (if they made an OS that would work on an iphone or ipad). The fact of the matter is you cannot because Apple controls what can and cannot be installed on the iphone or ipad. You may think you own the physical device but you do not because your fooled into thinking you do.
