Samsung may be preparing a CDMA OMNIA
Although Samsung hasn’t officially announced that it is working on an American-friendly OMNIA, it seems so, judging by its phones approved by the FCC. The number of the original model is i900 and FCC revealed two similarly numbered devices, the i910 and i907.
The i910 is a CDMA phone with Bluetooth and Wi-Fi. An included sketch really resembles the original OMNIA but is without a SIM card slot, same as in a CDMA device. If this one gets officially announced, it is expected to be released with Verizon Wireless.
The i907 sketch shows a different looking model, but it is rumored to be the AT&T-bound OMNIA.
Neither Samsung nor the carriers have officially announced that such models are in the works.
