i know there was a thread a few months back about the Bad ESN Verizon iPhones on ebay and if you could unlock them.. but that didnt really answer the question i have,.. as Verizon is a CDMA network.. if you were to buy a iPhone off ebay and get it over here to use on the Vodafone NZ network does that mean it would work? from what i understand Verizon lock the ESN for their CDMA network.. GSM uses the IMEI number correct? more specificly how does the "lock off / activation" process work? i.e. if you set your phone to factory defaults .. does a bad ESN have Anything todo with the itunes activation? if the phone is working when you get it from the US.. could you plug a VF sim into it and it would "just work" ?
