I have a question regarding unlocking and the iphones warranty. I am thinking about unlocking and jailbreaking via blacksnow and blackrain. If I then switch to a different provider with an early termination will the iphones warranty be voided? If I needed to use the warranty, with blacksnow and blackrain I could restore it to factory before bringing into the store but I would not have att service. Any one know how they would handle an iphone with no att service. I could always put my old att sim back in the phone but the service wouldnt be there.
