I got the same icons from somewhere else, more trusted ( not saying that the other uploader can't be trusted, just saying that looks more like they've been made by icon factory... UNLESS he works with them xD ) , which i think is the real source ;D :
IconFactory: Flurry System : [link] Flurry System extras : [link] Flurry System extras 2 : [link] Flurry System extras 3 : [link] Flurry System extras 4 : [link]
And they're actually Ipod/Iphone/Ipad OS flurry icons ( Exactly the same you find on an Ipod/Iphone/Ipad).
Anyways, your tut was very useful, nice to read, simple, [all the nice gentle word in the world ] And besides that, these Icons look perfect with this tut
