My iphone wifi hardware is dead. I've tried all the fixes but nothing. There's not even a greyed out radar icon at the top of the screen.

I want to take it back to the store and haggle a warranty repair. What state should an iphone which originally came with 1.0.2 be in? e.g. which bootloader? I've ziphoned it in the past. What's the easiest way to achieve getting it back to the original state?
