So I preordered my iPhone 5 and got it last friday morning in the mail. Opened it and all happy and dandy. Through these couple of days use, I kinda notice the top lock key is getting looser and looser. it starts to make more and more the wiggling metal clicking sound and I felt the lock is not as crisp as it was when clicking it (maybe this is all in my head. im just imaging it) but since I had the top lock key stuck down, not responding problem before with my iPhone 4, I am super paranoid about it. ALSO the real deal that set me to make up my mind of getting a replacement phone is that the front bottom right corner of my phone is kinda loose. You will feel there's a click when you press the from panel. it feels like something is not fitted and it's making the clicking sound when i press it. So i am going to the store to seek for a replacement. And im really concerned with all these new orders, are they going to have replacements for me?! and I am assuming Apple won't give me any grief about it and replace my phone?! Plus I have an AppleCare with my phone too. what you guys think? and im going to the store this Saturday and of course I will report back what happened!
