About 5 months ago i bought a k800i from o2. only a month before the phone had been anounced not availible and was last one in stock in any o2 store in the country.
the phone arrived at the shop 2 weeks before I bought it, which was 2 weeks after "out of date" and had added software. A year before this I bought the same phone, but it had less media than the new one. (I sadly lost the other one) I then recently realised the phone was unlocked as my mate was mucking about putting his TESCO mobile sim in and it worked. because the phone was not availible to make, does that mean that o2 coluldnt lock it?
