and anyways i think truecaller might be blocked its not connecting neither on wifi or 3G on my iphone anymore since 3 days strange...
first are you sure that Whozcalling is made by a Lebanese ? because literally i wasn't able to identify any number with it,in the other hand truecaller works for almost any number,plus it's working normally on Android it's not blocked.
and for a service like that i don't mind sharing my contacts phone numbers,i mean if you read every license agreement and terms of use and policy's you sign online every day you will realize that you are sharing much much personal info about yourself from location to basic info.
