I purchased a verdex PRO XM4-BT and a breakout-vx recently. I was about to connect u.fl Bluetooth Antenna (which came with the motherboard) to the verdex PRO XM4-BT, but I realized that the connector from the antenna doesn't snap to the board. Then I went to gumxtix.com website and found out that u.fl Antenna has some sort of "white tube" attached to the connector which it did not come with the antenna that I have (please, see http://www.gumstix.com/store/catalog/product_info.php?products_id=173).

Do I need to push the connector a bit harder to make the connection? Or is the "white tube" necessary?
