Hi, I have a customer that upgraded his iPhone 4 to 4.3.5. What is the best way to activate the phone at this point? ITunes reads "there is no sim card installed in the iphone you are attempting to activate". He was previously 4.3.3 with a Gevey Sim (for Tmobile). I cannot get past the itunes logo screen with the "slide or emergency". I really dont want to jailbreak since it tethered at the moment. So, please tell me how I can access the iPhone and get to the springboard at this stage (bypass the "there is no sim card installed in the iphone you are attempting to activate" in itunes). Much appreciated guys.
