I know that it has already been mentioned here many times. And I am one that hates bogging down a chat forums with questions that have already been mentioned. So please do not flame me because I already know I am breaking a cardinal rule. But I am getting ready to download 2.1 from sprint. I do not want to hand write over 120 phone numbers than re-enter them all after 2.1 has been installed. I have seen people mention an app they downloaded that backed up all the contacts. Can somebody remind me what that app is again and what do I do. Thanks again for all the help.
