i have a BB pearl 8130 for the Verizon Wireless network. i know that Verizon is stingy about GPS so i got this. since crackberry won't allow me to post the link, the ebay item number is 260270298010. it will connect and then disconnect. i heard that you have to change the port from serial to comm1. how do i go about doing that as i have search everywhere on it.
