Do not pull the "pull tab" in the inside of the phone. That is to help pull the battery out. It is also connected to a white sticker on the back of the phone which is part of your antenna. I figured this out cause i pulled the tab myself. I then was having internet problems, so i went to verizon store, and they wanted to try to take my battery out, well its impossible to pull the battery out without the pull tab. Then found out that the pull tab was connected to the sticker which i tore off a piece, and found out that i tore part of the antenna off. So now i have to wait for verizon to send me a new phone.
