I can search for "!" in the web client and the Mac OSX app, but it doesn't find any results when I search for it on my phone. Has anyone seen this before? I'm jailbroken, so I suspect some crazy tweak may be messing with it, but I don't want to wipe everything and it doesn't fix my issue. Can anyone with an iPhone try this for me and see if it works? Add a reminder with ! anywhere in the subject line. Search for it and see if it pulls your subject up.
