New 6700 won't use cdma driver

[lucatious]

I broke my 6700 and they replaced it with another 6700 from verizon. I went to use my usb duns modem setup after unlocking wmodem, and it would not let me use the cdma driver I used with my other 6700's. It uses an HTC Modem driver instead, but I am only getting connections speeds of 112kbps instead of the 230 I used to get. Has anyone gotten a replacement phone recently and had similar issues? Is there anything to worry about and can I tweak something to get back up to 230kbps? I have a spare phone, but I don't have insurance on it so I am not sure if I should go back to that one or not.
