i'm gonna tell you one small trick to find out if you're in someone's contact list or not.just go to any of your contacts and select buzz from menu.and buzz him/her.for example,h4v0ce- is in my contact list and i try to Buzz him if it says ,sorry,you are not able to Buzz h4v0ce-.it means that h4v0ce- deleted me and if i'm still in his contact list.it'll say,do you want to Buzz h4v0ce-?at start i asked those who deleted me that why they deleted me from their contacts list.they accused me of being a hacker but i told them the story.they got happy hope no one discussed it before
