Blue Little Triangle In Top Left Corner of Screen

When an app is using location services a right facing arrow will appear in the status bar, is that what you're talking about?

the triangle on the iPhone4 and 3Gs replaced the GPS symbol on the 3G. It just means that you have GPS service and is "supposed" to look like a compass needle. If you are migrating from a 3G or earlier, you now have the Compass app as a base application.

If you have a background app (since there's multitasking now) that is using location services, the arrow will show up at the top. You can close the app (double click the home button, click and hold on an app in the list, and close it with the minus symbol) and it will go away.

I'm pretty sure it's not the location aware icon, he's saying it's on the LEFT TOP corner. I got it too today.. it peels the corner off the top left of the screen, just a really weird thing. Def not a defect, just some kind of notification? whatever... I'd really like one of those Ohh what do you call it... PAPER MANUALS with the drawn diagram of all the status lights etc & their definitions. :P

I just saw it too, and in case you are interested took a screenshot. It's on an iPhone 4.

There's a screen capture here:

Not sure "answered" is correct for this post, it seems pretty likely it's a bug, even if there is a temporary way to get rid of it via sliding to the search screen.

For me it was showing up in the home screen, any app when you bring up the task switching bar, and in fullscreen apps (which is most annoying). Not intended to be an exhaustive list, just where I saw it.

And it still stays in the same physical screen location when in landscape mode, by the way (see screenshot of fullscreen landscape video in iTunes app).

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 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...

Page 17 and 18.

Any of those look like what you see?

whats the purple arrow on the right side?

I saw the blue triangle as well...the top left corner of my 3GS...was there until I slid to spotlight search. Running ios4 here. No jailbreak/unlock. ***?

Thanks for that i had the same thing - just slide to the search bar and it disappears..... weird :S
