Probably never. I mean, I am on iOS and as a developer I know how hard it is to get your code to run on iOS. Heck, security flaws that jailbreak an iOS device just via network/OTA is paid serious money for, there is no need to implement this.

I seriously ask the question what damage could a potential malicious app on iOS cause? There is no running in the background, so no exploiting while I don't use the app, no being part of a botnet when the app is closed. There is a FS sandbox that will not let you access another Apps data without being able to jailbreak etc. I think an auto-update is more risky on iOS than to live with an older version of the app that does its job (you never know what an update changes/breaks for you, and downgrading is not an option in the appstore).
