Just got the phone, and I no sooner setup my yahoo email acct and transferred the contacts and i was hacked! 2 emails were sent from my address to most of my contacts including myself. I only opened one of them and it was a spam ad for Canadian discount drugs. Some of my friends wern't happy. What did I do wrong? How can I avoid this? I immediately deleted my Yahoo acct ad haven't had any problem since, I'm afraid to use my email now. What to do?
