HI, I currently have a blackberry on orange contract but got bored of it so me and the other half bought 2 htc wildfires second hand at a good price. we r both on orange and his sim card works fine in his new handset but mine will not register that a sim card is in it (little icon at the top with a cross through the signal) we tried two places in town that hooked it up to their systems and they both said it cant be unlocked although it isnt actually locked to any network! its unbranded as is the box. I just dont understand how two phones that are exactly the same, one will work fine with an orange sim but one wont and apparantly nothing can be done! Any clues anybody?? any info would be greatly appreciated
