I done a phone swap from a Blackberry Curve 9300 to a Blackberry Bold 9780. I reinstalled everything and I had no problems what so ever. But when I tried to go onto Whatsapp, I had to verify my number again. So when it comes to verifying my number it I think "downloads" but freezes at 4:11 (1 out of 2). I have rebooted my phone several times and uninstalled and reinstalled Whatsapp. But nothing seems to work. What should I do?
