After upgrading to my iPhone 1.1.1 firmware, my phones speaker went totally bezerk on me. Every time I tried making a call the speaker would just buzz and buzz. Not only would I hear it but the person on the other end would too! It was one of those radio interference buzzes you get when your cell phone is near a radio.
Odd enough, when you put the phone on speakerphone or used a bluetooth headset everything worked fine. It was only when you used the built in speaker that things went nuts. I tried a firmware restore suggested by my friend Daryl but soon after the restore it started freaking out again.
So after driving me crazy for half a week, I took my phone into the Apple store where they promptly replaced it. It was really great to have such an awesome customer service experience. Nowhere else could I have done that! I’m absolutely an apple fanboy. Thanks for not only making such a great device but also supporting it so well.
