So why does my iPhone vibrate twice at boot?

My wife and I both have 16G iPhones, but for some reason when mine boots from power off, upon joining the AT&T network it vibrates twice in quick succession while hers does not.

No difference in any settings I saw right off hand.

Anyone know why?

Quad 2.5 GHz G5, 5 GB | 2.33 GHz MBP C2D 2 GB, Mac OS X (10.5.2)

Just a thought: Is your phone in silent-mode (switch on side of phone) while hers is not?

Nope, both in ringer mode.

Mine has been in silent mode before but is not now.

My iPhone recently started doing this as well. My original iPhone never did this when in ringer mode, only when on silent mode. Now that I have a replacement, it ALWAYS vibrates twice on boot, even though it's always on ringer mode.

Any ideas? It's not really an issue, but I just don't understand why it happens.

William Kucharski,

Is your iPhone set to vibrate in the ring setting so that it will ring and vibrate both when not in silent mode?

This is a setting in Settings -> Sounds.

Hope this helps,

Nathan C.

Nathan,

Since I'm having the same issue I thought I'd respond. My iPhone is set to ring only, not ring and vibrate. If this is abnormal, I've already reset the phone as well as restored it, but the vibration still persists.

I also have this so called "problem." It's not hurting anything, so why worry about it? I'm sure it's just a feature to let you know you've connected to the Edge network or something of that matter. No biggie, I'm not worrying about it.

Which firmware do the "vibrate-on-boot" phones have?

I realize it's not an issue, but I would like tonknow why some phones have this "feature" and others don't. I personally don't care for it.

That's exactly why I want to figure this out. I don't think this is actually supposed to happen.

MRCUR,

When it vibrates on boot is anything connected to the dock connector?

Thank you,

MRCUR,

If you restart it without being connected to the power adapter, does it vibrate?

Is the vibration similar to what you get when connecting it to the power adapater?

Thank you,

Nathan C.
