In the USA, This phone will NOT work with verizon. Apparently verizon will only allow whitelisted phones. I spent a couple of hours talking to various tech support agents at Verizon. The tech support agents had a difficult time accepting the IMEI number as being a real IMEI number. They were unable to get this phone to work on their network.
Vodafone is working okay for the FLX1s in the northern suburbs of Sydney Australia. One minor problem is that the signal level bar is greyed out. Very pleased with the FLX1s overall. Already my daily.
