Lock Screen on iPhone also said "Undo Typing"

[byziphone4]

Earlier today, I went to grab my iPhone out of the pocket when I noticed after I first pressed the home button to unlock it that the screen displayed "Undo Typing" and "Cancel" underneath it..with the "Slide to unlock" at the bottom as usual. So I hit the cancel button...not knowing why this was popped up on screen and then I slid to unlock the iPhone. Does anyone know why this could of happened? Bug?

Probably just a little bug? Maybe your SMS application was open under your lockscreen. Then it was still able to recognize on SMS.

It happens when you are at a typing place (like sending a text message) and you lock your screen. Sometimes you activate the shake to undo "feature" of iOS. It pops up a notification to undo the typing.

Well...the last apps that I had used were Pandora Radio and HeyTell....because I purposely remembered this because of this.
