I tried to update my WhatsApp with my new contact number, but it hung on me just now. Kept saying that it was "Connecting" when I waited for more than an hour but nothing happened. I have an iphone 4, running 5.0.1, jailbroken using the latest RedSn0w 10b4. Has anyone else had such a problem before? What could be the issue? I've already restored and re-jailbreak, but in case something like this happens again, is there an alternative solution?
