>aren't a lot of people who have jail-broken iOs devices, already by definition people who want paid apps for free?
Careful not to fall into the trap of conflating jailbreaking with piracy. There are many, many good reasons to JB not even counting apps that end in -ous. Google voice and SMS extensions, f.lux, theming support, wifi tethering, and a great deal more low level customization than Apple gives you.
As I said, I'm an Android user primarily because it gives me much more freedom without rooting, and the few iOs devices I have (and hardly use) are not jail-broken. But people I've met who jail-break their iPhones do it mainly to pirate apps.
