IPhone 4S locked to talkmobile?

Hi. I did not realise after buying my iPhone outright that it would lock to the first network sim inserted into it, which is talkmobile. Now I can't seem to find how to unlock it as the signal is rubbish! I phoned apple, talkmobile, carphone warehouse and Vodafone and they're all passing the buck. Nobody knows who or how to do it. Has anyone had a similar experience? What did you do, many thanks to all who can help

This should have been explained to you as only APPLE.co.uk sell truly unlocked iPhones which are the same price as those bought @ CPW

"Talk mobile" is a "MVNO" it leases these from VODAFONE network so you have the same coverage as Vodafone

I think that you are NOT going to win this one IF you bought a "Talk Mobile" tariff as whilst other handsets DO not lock, Apple do

So In my opinion ONLY if you bought a handset from CPW and then separate to that bought a sim only contract or PAYG sim do you stand a chance as CPW should NOT have sold you an unlocked IP4S without notifying you of its restrictions.

If there was a contract deal both handset & sim card then NO***

IPhone will lock itself to the network of the first SIM card that is used in the phone. Subsequently attempting to use it on any other network, for example by replacing the SIM card, may mean it becomes permanently unusable. SIM free iPhones can only be used with a UK-network SIM card, and will not accept foreign SIM cards.

***It is made "less" clear in the above which is applicable and given the fact that it is on offer at the same price as APPLE, there can be little defence by CPW NOT to mention this is All cases and not rely on small print.
