Went into CPW today, its a smallish store, the guy told me they are going to be getting 200 in and all the usual stuff. Then he dropped a bombshell - if you try to put another sim in the phone it will be locked! I asked him to explain and went over it a few times, from what he was saying he seemed to think that if you tried to put a different sim in the iphone, the iphone would be rendered useless, i asked him loads of questions like if it was software.etc. but all he said is that that is what they had been told. Im not sure ie believe this, i expect he has gotten confused, but he definitely seemed to believe that something else would happen above and beyond the phone being locked to the network and no other sims working in it. on a side note, anybody going to the grafton centre in cambridge to get their iphone. I was going to the O2 shop but they knew sweet FA so im going to the CPW store i just talked about.
