hey guys, the bottom half of the screen is no longer working on my iphone and i want to take into the apple store to get it switched out, now my problem is that i need to revirginize it so that they wont be able to tell it was unlocked. i cant downgrade because i wont be able to get into my wifi menu to use putty, is there anyway for me to virginize 1.1.1 without touching the iphone and without downgrading? the iphone remembers my home wifi so i can putty into it now. i need help asap as my appointment for service is tomorrow
