How to tell if your still rooted

[Bizzare]

I went in Sunday to get my screen replaced at my local sprint store in Redlands. i tried running my WiFi Hot spot and i was blocked as well as my Clockwork Recovery. I thought maybe it was just a bug but this Morning I tried installing the update through recovery and I got a Red triangle with a red ! in the center. I can't even run my Rom manager can some one help?????? Please, Need Help.

Can't say what happened at the sprint store, but if you want to see if you still have root then downloand android terminal emulator from the market (its free). When in it you'll see a $. Type su then enter. If you are rooted then it will change to a #. If it doesn't then you lost it

Another way to tell is to turn your phone off and boot into the bootloader by pressing vol down+power and look to the top left. If it says S-on your definately no longer fully rooted.
