For some time now I’ve experienced oddities with the call waiting beeps on the iPhone. When I first noticed it, it was on a call between myself (iPhone 1st Gen) and a friend (iPhone 1st Gen). I could hear the call waiting tones when he had a second call coming in, and he could hear my call waiting beeps when I had a call coming in. It was kind of a nuisance, but I never tried to troubleshoot it.
Now that I’ve upgraded to the 3GS, the problem is much worse. So bad that frequently, the party I’m talking to thinks that it’s their own call waiting beep, but then they see that no call is coming in. It’s not a huge problem, but I decided to try to fix it.
I called Apple and spoke to a level 2 Product Specialist. She was both amazed by the problem and very interested. She got ATT tier 2 on the call and I demonstrated the problem to them repeatedly by calling my iPhone from my work phone. Conveniently, it’s one of the easiest problems to demonstrate to a tech over the phone. The ATT tech did a bunch of stuff to my account, but had no impact. They could still hear loud and clear whenever I had an incoming call.
After we let ATT go from the call, we wised up and I popped my SIM into a 3G phone made by LG. Voila. Problem gone. This confirmed that the problem was indeed local to the iPhone and not network based. Next we tried with the iphone sans wired headset. Problem gone. Just like the LG. Next I tried Bluetooth. Worked perfect. We both agreed that it must be the wired headset. I set a Genius Bar appointment and hung up.
Before I left for the store, I realized that I had a brand new wired Apple headset that I had never used. I plugged those in and to my amazement, the problem was back! At this point, it seemed that the iPhone itself was at fault, and was causing the problem by the way that it handled ANY wired headset.
At the Apple Store, they were also amazed and claimed to have never seen this problem before. This led me to believe that I just may have a defective phone. They pulled a brand new 32GB 3GS off the shelf and swapped it out with no hesitation. I didn’t bother testing at the store, because if this didn’t fix it, there could be no resolution without involving engineering.
I must say, however, I was a little surprised when I made a test call on the drive home and the problem was not resolved. Exactly the same problem. It’s interesting to me that no one is complaining about this, considering I just went through two pairs of Apple wired headsets, and two iPhones with no change in the problem. It must be happening to nearly everyone with a 32GB 3GS, and possibly more.
The circumstances are:
Using an Apple wired headset on an iPhone 3GS
Active call with party A
Incoming call from party B
Party A hears the beep from the incoming call loud and clear
One entertaining side affect is that I got to try the “Remote Wipe” function of the new iPhone OS 3.0. I used it on the outgoing 3GS and it took about 5 seconds, after which, the screen went black and it rebooted, then asked to be activated.
