Ever since I jailbroke my phone it does this weird thing where it won't let me press the end button and I have to wait for the other party to hang up. Is this a bug with jail breaking or ios6.1? It's never done this before and it's pretty annoying. I don't know what I've installed to cause this. I have zephyr but I disabled it in the phone app so I can't think of anything else. Any suggestions?
