The government has approved a new version of the Flip for use in the U.S. This CDMA variant will work with Verizon Wireless' and Sprint's networks, and adds EVDO 3G to the mix, something the GSM version of the Flip lacks.
The only other feature confirmed by the FCC at this time is that the Pearl Flip will also have Bluetooth on board. We can probably expect most other features of the Pearl Flip to appear on the CDMA version. It has a 2 megapixel camera with video capture, microSD card slot and 3.5mm headset jack.
RIM has not officially acknowledged this phone, nor has Sprint or Verizon. Even so, it's likely to be coming to a Verizon or Sprint store near you in the not-too-distant future.
