hi guys, im new to this whole forum thing so bare with me please yesterday i was going out for a run, it was about 85F , i was running for about an hour and had my iphone 4 *2 weeks old(white iphone). and when i stopped to reply a text message the back of my phone was wet. keep in mind it was really hot and i was wearing sweatpants. after that my home button stopped working. it would make random face-time calls and activate VOice Control all the time. so i was checking my phone and i see a red/pink color where my iphone's dock is. but how when i never dropped it in water.my headphone jack is clear (white). haven't submerge my iphone in any type of water. i have a meeting with apple tomorrow at their retail store. will they replace my iphone? what do u guys think?
