After applying 1.17 to my UNLOCKED Cingular I ended up with firmware version 1.51 and software version 1.17CNG and an apparently LOCKED Cingular 650. I reapplied the Subsidy Unlock Code, but the phone still seems to be locked. I don't have another carrier's sim card to try, but before the update, once the phone was unlocked, under phone info I had an additional choice, "Choose network". This option is no longer available. Also I had DUN and that has disappeared, as well. Does anyone know how to tell if the phone is still unlocked? I don't want to get to Europe and not be able to use a prepaid sim card. TIA
