PEOPLE, does someone have a higher res burst "B" or the skills to make it again in a higher resolution?
I converted the "B" from the OP into an SVG image, which can be any resolution. The SVG code for the image is:
<?xml version="1.0" standalone="no"?>

</svg>
I also scaled it up to 500x500 and uploaded the png:
I just used a tracer to convert the PNG into an SVG, and then adjusted the colors. So, the paths may not be a perfect rendition of the original logo (it does look slightly different to me), but it's the best I could do with my limited skills, and it's still way better than the pixelated logo you'd get otherwise. If the original creator could chime in and provide SVG logos for all the icons in the OP, that would be ideal.
