If you look at the battery cover on your 8830 you will notice it says Qualcomm 3G CDMA. The 1XEV indicates you are on EVDO. 1X is CDMA. You will still receive data as long as the letters are capital.
I would imagine the Storm would show 1XEV when in a 3G area and 1X when not as the current BlackBerry devices do.
