What we find in the filing is the CDMA iPhone we've all just recently been introduced to – with test results for CDMA/EV-DO Rev. A on the 850/1900 MHz bands. In addition, we find results for Bluetooth and Wi-Fi in the the filing – but of course, there is no indication whatsoever to indicate support for GSM roaming.
Now the only thing to wait for is for the actual release date to come around so Verizon customers can finally experience the talk of the town with the iPhone 4.
