In previous versions of iOS, you had to slide to unlock in one very specific location. Now? Oh man.

You can slide to unlock here:

or here...

even here...

but surely not... here?

Okay what about... here?

Yes. As long as your gesture is vaguely left-to-right, you can unlock from anywhere on the display. It never made sense that the unlock was at the bottom the whole time, since your hand doesn't naturally rest there when you hold an iPhone. SWEET RELIEF.
