so i followed o2's advice and went with the 3gs, swapping sims with my 3g. was about to send my iphone off for recycling/reuse, and so decided to to an "erase all data" on the 3g. however it looks like it lost power before it could complete the 2 hour process. now all i get when i press the power button is a black screen with a white apple logo. have left on charge all day and tried numerous button combinations with no luck. so is my 3g bricked?
