Blue Little Triangle In Top Left Corner of Screen

Posting this from my touch, I'm looking at the little triangle right now. It doesn't seem to be a stuck pixel, as it has a virtual shadow. Haven't yet done a spotlight search...

Same thing happened to me yesterday and this post is all that seems to talk about this triangle out there. This topic is definitely not answered nor is this question solved.

The triangle did not disappear by sliding to the spotlight search, and it vanished while the iPhone was charging. And even though the manual is not on paper, there's no reason while it should not appear in it. Pages 17 and 18 would be the place to have this information.

I had the same thing happen to me tonight. Rebooted the iPhone and now it's gone?

Solar flare?

I just had the exact same thing. Was updating some apps when I noticed it, may not be related. Swiping to spotlight got rid of it.

Same here: brand new (opened 30 hours ago) iPhone 4 running iOS 4.1. this is most definitely NOT solved. not impressed.

Strange that no one knows what it means.
I have seen it as well on my iPhone 3Gs running iOS 4.1.
Sweeping over to spotlight/search window clears it.

I just got one on my screen, and I also have the iPhone 4 + latest software. I moved over to the spotlight search screen just as someone else on this discussion said they did. It instantly vanished. There is no pixel damage like some say... I have no idea what it is. I had just closed out of my camera and locked my phone 5 mins prior whrn I double tapped for the music and it was there. But I will try and research what it might be caused by... At least they disappear... (just found it odd that it didn't disappear in any screen until I went to the spotlight search) I didn't think of rebooting...
