@btcontract, thanks for such a quick update to your icon; I'm sorry we didn't catch that before merging.

LGTM.

These commits should be squashed into one. There is no need to replace and delete the icon 4 times in 5 commits (one commit being empty).

[crwatkins]

True.

Similar PR from @schildbach replaces icon in one commit, should I just close this one?

[schildbach]

For some reason, though this PR is merged it didn't become active on the live page.
wget https://bitcoin.org/img/wallet/simplebitcoinwallet.png
fetches the old image.

Yeah, this looks strange, and apparently didn't work.

Well this is embarrassing. I've used github web interface to upload a correct icon last time because was away from working machine. Here's a new PR which undoes this one and adds an icon avoiding web interface, hope I did it right this time: #1321

I think it's a webserver synching problem. The git repo has the correct icon.
