why is my screen black and my phone locked out?
Not much that can be done with a dark screen. Let's see what we can do to get your 4s working properly, iamgjn. This is very basic, but have you tried just holding down the power button and home keys simultaneously, until your phone restarts? With regards to the lock out, did you have password protection services set up on your 4s?NicandroN_VZWFollow us on twitter @VZWSupport
