SVN didn't cooperate.
This doesn't work:
svn commit email@example.com -m "icon changed"
This is how to do it right:
svn commit firstname.lastname@example.org@ -m "icon changed"
Notice the added "@" in the end of the file name.
I hope this solves the problem in iPhone and iOS of how to commit the email@example.com file in SVN.
Good luck! :)
