I had a 32GB iP4 and went to see a Genius this evening regarding a signal issue which I believe went beyond antenna gate. My bars wouldn't give me a consistent signal, it would drop from 4 bars to 2 in just about every where I went. I never had this issue w my 3G. So, I went in and explained it to the Genius, he tells me that the same thing happens to him. I also told him that I wasn't dropping any calls because of this, as of matter of fact, I would have one bar at times and ppl would tell me that they heard me clear. So he suggested not to fix something that's not broken, and I agreed. I didn't want to end up with a replacement and deal w another issue.
However, I asked him if I wanted to exchange the 32GB for a 16Gb (iP4), would it be possible but without being put on a priority list, the Genius says yes they will do it. Long story short, I got to exchange it for the 16GB BUT notice I'm getting good reception (5 bars). Now, the phone is still on iOS 4.0 and not sure if I want to update to 4.0.1. But just thought that I'd share that with you guys.
I also noticed that the phone serial number begins w 7 instead of 8. I asked him out of curiosity why was that, and he explained that number represents the factory where it was manufactured., which could be a possibility. So I'm starting to maybe believe that perhaps apple is doing silent recall..? I mean it's just a theory but so far no problem w signal.
Discuss amongst yourselves.
