Hi I have a spanish iphone. I have previously jailbroken it so that I can use a UK sim card. However after leaving the phone with my ex to use she decided to reset it!!! So now I can no longer use it!!!! So my question is, can someone please tell me how to do this on a macbook using itunes 10. I have tried googling this... however all of the links are working for iphone 3gs and not 3g! Any help would be mightily appreciated. Thanks EDIT I do know know what firmware its using. At the moment all the iphone will do it tell me to plug into itunes who then tells me that my sim is not supported!
