"The Samsung SCH-i770 was recently approved by the FCC. Documents seen on the FCC site provide some interesting details about this device. It has dual-band 850/1900 GSM and dual-band 850/1900 CDMA radios. It also has other bands (possibly GSM 900/1800), but it could not be confirmed what the exact additional bands were in the existing documents."
All evidence points to this being an international-capable phone on Verizon styled after the i760. Business users on Verizon needing a new Pocket PC Phone will want to keep an eye on this. If you're curious, you can check out the FCC documents yourself.
