I have an iPhone 4 (Verizon) and I do not see any place to remove a SIM card. The phone died during an OS upgrade with error message 4005.
During an upgrade of of my iPhone 4 to OS 7.1.1 it stopped mid upgrade with the USB sync cable and Apple ICON on the screen and a 4005 error message on iTunes. Now the phone will never proceed past the above screen when powering up and iTunes does not reconize it.
