I recently bought the htc tmobile G1 from my friend. He gave me the phone with the battery, that is all. I manually added the contacts in 1 by 1, only to find out that in order deeper in to other access's i have to login "google sign in". I noticed that it was under his gmail address and needed to input pw. Q1 : How do i reset the login to my gmail? Q2 : Since I only have the phone and a usb cable to connect to the computer, how do I back up all the contacts that I manually inputted? *note* there is NO microsd...I only have my own sim and usb cable to hookup.
