Okay, so I'm on a jailbroken 1.1.3... I've tried two methods, both do not work. 1) Download the preferences.plist and proxy.pac file and put them in your iPhone. I've tried this, and it didn't work. Yes, I put them in the right places, and no, I haven't tried setting the premissions to 755. I currently don't have wifi, so I can't test if that is the problem. 2) Download the app from Installer. (5.99 TZONES hack) I don't know why this doesn't work, but it just doesn't.
