I just had a scroll arrow show up on my home screen ar the bottom right corner. This has never been there befor. What did I do to make this happen?

What does it do? More info is needed. Is it a program icon? Did you sign up for any push services? Are you are on a corporate BES where they pushed a program to you?

My service is on T-mobile. Its not a big icon its a very small arrow in the lower right bottom its a scroll down arrow but its never been there befor today and i didint download anything today.

I want one,
I'm T mobile and its my right to cop for one as well

Open your browser and see you see any bookmarks called "Push" XXX

What BB theme are you using. I've seen it before when you have too many icons to fit on the homescreen. Scroll all the way to bottom of the screen. Are there more icons at the bottom that weren't shown before? Once you scroll all the way to the bottom, the bottom right scroll arrow should dissappear but then you'll have a scroll arrow on the top right of the screen. The scroll arrow just tells you there is more on the top or bottom.

It's gone I don't know what I did. But its gone.

I would bet you had a temporary icon like the Registration icon. With that temporary icon, you had too many to fit on the screen so you had to scroll down to see the rest.
