Using iphone 4S on CDMA & GSM networks

[colonelbutt]

I am buying an unlocked iphone 4S

Could I register it with a contract for verizon in the US and also a contract for O2 in the UK, as both the radio systems are separate ?

i.e. so in the US it would use Verizon and in the UK it would use O2 ?

thanks for any ideas in advance

The small print on the Apple web site says that CDMA cannot be used on an unlocked phone, so no.

You'd have to buy a Verizon version and pay their extortionate roaming charges when you are in the UK, or buy two phones. You'd have two on contract anyway, as the contract includes the subsidised handset.

No.
You can use an unlocked 4S only on gsm networks.

thanks

perhaps someone will write some software for a jailbroken 4S sometime in the future

I have used CDMA phones in Israel before, and all the operator needed to do was to register the id number of the phone

You're thinking of ATT, who has always previously locked their iPhones to their own SIMs.

Verizon has always allowed the GSM side of their world phones to be unlocked, so you can use non-USA SIMs.

What is unknown, is whether or not Verizon or Sprint will allow any iPhone they didn't sell, to be registered with them.
