On the same whatsapp website, on the FAQ's, it says that your device doesnt have to be jailbroken in order of being able to verify your number: http://www.whatsapp.com/faq/en/iphone/20902747 Your phone has full Internet access with a strong signal. Try opening a web page to make sure. Your phone is not roaming. Your phone can receive international SMS messages. You are not using an unsupported device such as an iPod Touch or iPad. Your device is not jailbroken. When I try to verify my number, it dosn't send me any code nor it calls me. Is it because I am jailbroken?
