iPhone 3GS mute / silent button jiggles around

The switch on mine is a bit loose, too.

I got two 3Gs's today and yes both switches jiggle...
Also my sleep wake button on one of my 32GB is noticeably more flush to the case and thus actually harder to quickly sleep or wake the device...the 16GB is a bit higher set so little easier but I guess I'll manage 🙂

Mine is too. Doesn't seem to be affecting anything.

The most annoying aspect of the loose switch is that it makes an audible jingling sound if the iPhone is shaken or tapped forcefully enough. The switch on the 3G model wasn't loose--hence, no jingling.

If the switch is loose you should take the phone back and exchange it for a new one. The switch on my 3GS is nice and tight. The switch on my original iPhone was loose and it eventually stopped working (about a year later).

While in silent mode, my switch wiggles, too.

mine does aswell, i just hope i dont have to worry about it later on because it doesnt seem to be a drastic jiggle? it just moves a tad when i tap it with my fingernail.

I also just returned from an Apple store, myself.

I had a reservation with a Genius for this afternoon and arrived early to inspect the store's display models. There were eight 3G S units on display. The silent switch on the majority of them felt similar to mine -- some slightly better, some definitely worse -- with only two being firm.

Discovering that, I considered canceling my appointment.

Next, I compared the displays of each of the eight display units (full brightness with auto-brightness off). All but two had a warm, yellow-ish tint, similar to my 3G. Ew.

Being extremely happy with the crisp, cool screen (like my 2G) of my current 3G S, and not liking the odds of getting a bum replacement, I decided to cancel and live with a silent switch with a little wiggle.

I guess I can rest easy knowing that a little give in the silent switch is likely an unfortunate by-product of mass production and lax QC.

Now all I need to do is find something else to obsess about...

I just found this out as I was about to use my iPhone. I was also thinking that it was just part of how the phone was made. I am wondering if Apple has hard about this. This seems to not be to good as I am not the only one to have this issue. On my phone I only find the silence button to jiggles when in silence. Is it worth going to the apple store about this tomorrow? What is everyone doing to make sure that there silence button dose not get worse?

Yes, I just tested on my 32Gig Black 3Gs and it does "jiggle" when I have the mute switched on. No problem when I have the mute in the off position. Must be design/production flaw.

I have the same issue. I thought I'd do a search expecting not to find anything out. I'm surprised that there are others having this same issue. I feel less weird for noticing that. My switch doesn't seem loose enough to warrant a return, but it is a little annoying that it makes that jiggle sound when the phone vibrates or is tapped. Does anyone also feel that the motor that vibrates the phone is a little stronger, too?

I went to my genius bar with 3 complaints about the iphone 3Gs.
First: the mute button was loose. I was told it was a new feature. hahahahaha
Second: If you run you finger down the left hand side the plastic was not flush with the metal. That was accepted.
Third the metal bezel stood proud of screen and cuts into the ear when on a call. That was also accepted as a fault.

So they ordered me a new phone. Now, when I tested all the phones on display about 90% of them had all 3 faults... What's up apple.. Bad production run and the QA gents over in Asia were all out for a national holiday????
I have an original 3G iphone so all 3 faults stood out really quickly. For me the sunken display is a killer and requires a general recall.
