I am looking in to buying the extended battery for my thunderbolt. I was thinking of getting the HTC Extended Battery w/ Door. I read some place that the antenna is part of the original battery and door and not part of the extended battery and door. My concern is i wanted the extended battery to use for gps navigation and i will be in the Disney parks for countless hours and not wanting to run out of power. Can anybody give me any insight to the antenna situation.
