Apple will want to rapidly patch this either way. They still see it as a large security flaw, even if it needs a physical connection, and they hate jailbreaking.

4.2.1 is still vulnerable to a remote safari exploit, capable of gaining root. There's no way for iPhone 3G users to update past that point. They don't care about security.

Do you mean the JailbreakMe web-based exploits? JailbreakMe is not available for iOS 4.2.1. It's available for 3.1.2-4.0.1 and 4.3-4.3.3 - see http://en.wikipedia.org/wiki/JailbreakMe#Compatible_iOS_vers... for details.

To be clear, you're arguing that [Apple doesn't show adequate concern] about (a theoretical) security (risk to a handset that was discontinued 2 years, 8 months ago)?
