I have been getting a ton of hangup calls and wrong number calls recently on my blackberry...I just discovered that my number is somehow close to a contact number for On-Star!! Are you kidding!?! I got my blackberry STRICTLY to check e-mail and to send pictures to vendors...NOBODY has the phone number...I don't even know the phone number off the top of my head...I have a separate cell phone for all calls and texts...how irritating!
