Here is video that I-Phone Clone with Improved feature from China already. I guess we will never see that phone in US but who knows, you could get one from ebay for cheaper price..

Just like any business, you do not have to create wheels to make money. You just need improve existing idea and make it better to make money. Not everybody can come up with multimillion dollar idea, so borrow one you like and make sure you could make it better.

For example, I am currently borrowing someone’s another million dollar web site idea which looks good at least to me and I am trying to copy over and make it little better. I will post original site and mine later when I complete my site which is around 80% done.
