Went in to Vodafone store today to cancel my iphone plan to be told

1) they cannot cancel an iphone plan in the store
2) apple will take my phone off me if I try
3) Telecom CEO has been contacted by apple and threatened to remove all iphones from telecom ... (or else!)
4) Every iphone on Telecom is going to be [sic] wiped and blocked from telecom network.

Now,

I have been on an iphone plan for about a year now and have just been too tempted by having 3g everywhere (dammit I am sick of 2g dropdown, but I digress) and the telecom credits (and that prepay is better value than my vodafone plan). When I joined vodafone I was cautious (2 year contract) and read all the terms and conditions and all that. My understanding, is that I own the phone outright, and they cannot take it off me. Secondly, I can run it on whatever network I want, I did not enter into an agreement to use my phone on any network, I entered into an agreement for a simcard, with some minutes, with some data. As allowed for in that agreement I will cancel it (at a cost of some $200 or something, which I completely accept).

My gripe is the Vodafone store workers behaving completely unethically and as it seems to me, trying to bully or scare me into staying with vodafone. I would clear this up but I apparently cannot cancel without ringing a customer services number they gave me that I cannot ring on a sunday.

I would really appreciate your views on this?

Cheers
