I think there's a lot of confusion from people who think that as soon as the iPhone came out - everyone was copying them when the reality is - many were working in tandem. Apple just got there early (not first) and was wildly successful. That's not to say that since the iPhone came out - there hasn't been companies trying to rival Apple's success whether on their own or by adopting similar features.
I'm sure there is some truth in what you say but I think you're over playing it.
If other companies were close and had similar technology almost ready, what happened to it? Why was the iPhone so disruptive? Why why major established manufacturers left in the blocks? Where are their patents? Where are the phones? Where is the evidence?
Even Microsoft had to pretty much go back to square one and re-invent their mobile platform with Windows 8 and (arguably) we're seeing evidence of what Samsung did.
