Long dull story by basically my dog ate my brand new contract phone about 2 weeks into a 24 month contract, I had no insurance...I bought another really cheap phone from the car phone warehouse and just popped the sim in and it was fine. However I would like to get a slightly nicer phone ( as dog chewed this one a bit as well - although has now grown out of this habit thank god) and as I still have 1 year to run feel like its worth doing. I am looking on O2 website at a sim free lg viewty which looks quite nice and isn't stupidly expensive - I can also get it from amazon even cheaper. Does this mean I could just buy it and put my sim in? Could I buy a refurbed iphone and do this?
