The other way around actually since the iPhone came out after it. But yes, if you were sent back in time to 2007 you would notice the similarity. I ran a mobile phone news website at the time, the similarity was definitely talked about (see the Engadget link in my OP).

The original iphone had a clean aluminum casing whereas the prada used generic black plastic casing -- I think people could tell them apart back in 2007. Practically all phones on the market were black. The differences were even bigger if you used either device for more than a minute.

And Apple quickly went to all black... The differences between anything Samsung makes and an iPhone are quite apparent too if you use them for a minute.
