I believe it is the GSM dialer in the ROM that keeps connecting to the data network. You can replace it with the CDMA dialer and you get a more 'stock' look, (i.e. the Data Arrows work correctly, they only flash when data is moving).
You lose some of the GSM dialer fun things like send text when you ignore a call, but the dialer is the one built for the CDMA Verizon phone.
You can find it at

He posted it for users with his wm6.5 ROM but it is the Vogue dialer and I use it on my phone with his V1.15 ROM and it works fine.
