As a very happy owner of both a jailbroken iPad and several rooted android devices, I can only tell you how incorrect that is. Sorry.
How many android phones cost more? You realize he's talking about on contract, how most people in North America seem to buy phones. Of the top of my head, I can only think of the Thunderbolt and the Streak that sold for more.
I'm sad it took 6 pages to ask for this. I'd love to know. It looks good.
Basically, the iPhone is no where near the level that Android is in terms of custimizability, jailbroken or not. (I own an iPhone 4 that I jailbroke, fyi.)
