Got an Epix? Noticed that when the sucker is in standby/powersave mode, no matter what you do in the notifications settings, emails just won't make noise? It's not your fault. No no no, it's not your fault. It's not your fault.
Now that you've let that angst out, go on and grab the pdf explaining how to download the hotfix. Or really, just grab the cab file from here (hint: click the 'etc' link at the very bottom of the software tab). This direct cab link, but don't forget that since it's a cab and not a ROM patch, you're going to need to reinstall after a hard reset.
