Hey Everybody This is a stupid question but just wanted to see if anybody had an answer. Bought a iphone 4 off CL and luckily got the box and everything else. It's a week 30 something 2010 model and I'm noticing that there might be an issue with the proximity sensor and the home button not responding as quickly. So my question is..when you take the phone to apple for warranty repair, do you have to take the box with you? I don't really need the box or anything but just seeing if I need to take it with me. Thanks for humoring me with this idiotic question.
