Rubbish, been trying to use whats app on my laptop because i don't have a phone signal but 1gb hyperoptic lan. as the phone doesn't have a signal the pc cant use whats app. What's the point of having a app for a pc you cant use unless the phone has a signal as well? what idiot thought this one up? If i wanted or could use the phone why would i have a the app on a PC?? Whoever came up with this idea must have escaped from Jim Hendersons workshop with the rest of the muppets.
