Hey folks. I have a new iphone 4 which was provided as part of a new business contract through a telecoms company not Orange. The Orange sim came separately. However the 3g web access is painfully bad as compared to my old 3gs iphone on T-mobile. It's pretty much useless in most parts of London. Which brings me to my question. Is there any way of telling if my new iphone4 is unlocked without having to buy a new mini sim card? Any way of checking through the firmware or something? I was seriously thinking there was something wrong with my phone but all my colleagues on Orange also have the same problem. We were out on a course yesterday and I had my old 3gs whilst everyone else had their new iphone4 and I was the only one able to access mail and use the web the whole way there on the train and at the actual centre itself, which a lot of my colleagues were none to pleased about. I presume it's Orange being a bit rubbish and not the new iphone4 having a weaker signal reception? Thanks guys.
