i am from Singapore and been using the iPhone for 2 months now. I just noticed that i got a dead pixel on my screen yesterday. After emo-ing for awhile, i did some google searches and the only possible solution is to replace it with Apple? However, iPhone will not be here officially till next year. I will be going to London for holidays for about a month. Is the ANY way at all that I can replace my iPhone there? Btw, I did not receive any warranty card from Apple in my iphone box. Just some warranty notices. Do they check my serial or IMEI to determine my warranty status?
