Hi!<br /> <br /> Yesterday my up volume key got stuck somehow. It won't click and you have to push very hard in order for the volume rocker to register. I got this phone in early March after my original iPhone 4 was replaced. I no longer have AppleCare because my year was up in March, but I'm assuming I still have the additional 90 days left of the replacement iphone warranty. My question is: Is there a way I can fix the volume rocker without opening the iphone? And if not, is there a high possibility that Apple will replace or fix my iPhone because of this defect? Thanks in advance.
