Hi all, I bought an iPhone 4 that I was told was factory unlocked off Apple. When purchasing I was shown it working with an orange sim and a T-mobile sim. When I got home I got my Three sim up and was given an "invalid sim" message and thought it may have been because I cut the sim down too much so I tried again with a T-Mobile PAYG sim that have - that worked A PAYG Tesco sim gave me "invalid sim" when I cut it down too. I'm guessing 1. I have been stupid because Orange and T-Mobile are now one network, meaning a sim card from one network will work a phone from the other and vice versa. 2. I'm butchering sim cards and need to get a 'proper' micro sim from a store. I know it is scenario 1 but was hoping for someone to tell me different. Oh it's on 4.0.2 so I can't JB it to allow my Three UK sim to work on it. DOH!
