Hi guys,

I'm new to the iphone world. I've had it for a month now. I have a question about syncing contacts. When I first got my phone i connected to Itunes and had it sync my contacts with my yahoo email contacts. Since then i've added numbers to my phone but when i sync my phone on itunes it deletes the names I added to my phone. why does it do this and how can i avoid this? Do i need to add every new number i put in my phone to my email contact as well so it doesnt get deleted when syncing???
