Hey there, here my first entries. The third entry could be used seperately as a iPhone Button.
Any feedback very appreciated!

(This comment references Entry #126)

Very cool... I actually like the icon quick a bit. #128. The shape of the "b" is cool.

The circular lines looks great at a large size, but when shrank down to 20x20 pixels (I know, that's small), the "b" kinda disappears. Possibly try the shape of the regular "b" with out the circles if you have the time.

Thanks! I really appreciate the entries.

Thanks for the feedback! Here my revisions. The circular lines are still recognizable down to 20x20 pixels!
