Nearest Apple store is an hour and 30 minutes from me so seeing as how I'm going up there anyway today, I made an appointment with a genius. My big beef with the phone is the proximity sensor and if I'm in a call longer than 5 minutes, I can pretty much rock the phone off my ear ever so slightly and the screen comes on. My only fear is that once I get it there, the genius won't be able to replicate my problem and tell me it's fine. Basically I'm asking for advice/tips on what to say to this guy (I've never been to an Apple Store and I haven't heard how nice the people are in the Florida Mall) so I don't overreact to whatever this guy is going to say to me. I'm also curious to know if anyone else has had Apple replace the phone for this specific issue because I seem to be the only one out of my batch of friends that is having this problem. Even when I use their phones, I cant seem to find an issue. Again, any advice is greatly appreciated.
