Z500a HELPPP : (
1. If that was the case Cingular would stop offering Bluetooth phones period.
2. If that was the case, the Sony Ericsson s710a would also have no Bluetooth, considerings its EDGE equipped as well.
3. The European/Asian version of the z500 also doesnt have Bluetooth.
4. Let's not get Cingular mixed up with Verizon Wireless.
Bottom line, Sony Ericsson obviously chose not to integrate Bluetooth into the z500a, nor the z500i.
