Steffwiz is the maker of them. I emailed him weeks ago asking if he still had them and if he could send them to me. He never got back to me.
Those were the best sliders. Very clean.
@ Spittflmamz : They were black in the middle and have a metallic border. The border was chrome for the unlock, red for power off, and green for answering a call.
I'll make some of my own and post them back here. I don't know when I'm going to be done. Could be done tonight.
Someone might still have the file on their phone. If you do can you post it?
Update:
Alright here are the metallic sliders I made. There are tons of colors to choose from.
