Well, it seems that Apple has been rather prompt at fixing (again) the flaw that allowed someone to access lots of private data on a locked iPhone by double-tapping the Home button while on the "emergency call" screen.
The iPhone OS 2.1 update that has been just released fixes it: now when you double-tap the home button, it simply brings you back to the "Unlock" screen.
More 2.1 goodness as we explore the update.
