In the latest version and beyond, you can upload the log directly by
going to the info/stats page (tap the "i" in the top right corner of
the app on first startup (you may have to disable the autologin or
"radio only" mode from Apple's Settings app to be able to get there.
Then scroll down to the "debug log" row, and swipe to delete it. When
you tap "delete" it will ask if you want to upload it before deleting
it. Please say yes, and then let us know that you've uploaded it.
You can still send it using the link above if you'd like.
