Hi all, I feel that what David and Neil have stated are more correct for
what it's worth. I personally have not looked up or researched whether
or not it's a good idea to force a reboot via the power button being
pressed multiple times, but on the surface it just seems silly and not
safe to me. At least when you do the power button/home button for 12
seconds, it's giving the iOS system a chance to try and do what it can
so that files and data are not being accessed while the phone is forced
to reboot. This is why it's probably a several second process.
Additionally, it could be that it's on purpose so you don't accidentally
reboot your phone without meaning to.
Lastly, folks, please update the subject lines. <smile>

Hello Grant,
My friend is some sort of developer. You can argue for crashing the springboard
all you want saying it will not corrupt any code. My friend says there is a
very slight chance that it could corrupt code. I prefer not to take that
chance. I have corrupted code in a pocket pc which then required me to do a
complete rebuild from my computer. As this takes time which I prefer not to
spend in such fashion, I choose not to take the chance.
An Apple support person is the one who told me that the home and power buttons
simultaneously for 10 to 12 seconds reboots the phone and properly restores the
driver stacks. From my timing of both restarts, the reboot takes longer for
booting up than the power cycling for booting up.
To be precise, the higher level support specialist told me to first turn the
iPhone off then on, and once it has come fully on, do the reboot.
Sorry, but I trust both of these people over what you are saying on the list.
My developer friend is a software engineer. The Apple tech support person was
in the higher tier of support.

Hi Neil, the twelve-second holding down of HOME and POWER is a forced
reboot, rather like pressing the REBOOT button on a PC. If system
corruption could occur on an iPhone using the other method (which as
I've said I'm skeptical about), then it most certainly could occur
with the reboot method as well, which does not shut anything down.
Crashing your springboard is not "a forced collapsing" of the iOS
platform; the springboard is one part of the iOS architecture. It's
the part of iOS from which apps are launched. It does not store any
critical user data.
I think there are a fair few misconceptions about this topic on list.
I don't mean to be argumentative but it is important that people
understand them, and that if you have a theory (such as that data
corruption could occur) that you make clear that it is just that--a
theory. People who are stating this theory have relatively little
technical data to back it up--case and point, the "forced collapsing
of the iOS system" statement, which this is not.
Warmly :)

Adrian,
I agree very much with David's suggestions, the stuttering of Voice Over is
a classic symptom of an over full App Switcher and / or a handset which is
rarely power cycled.
My strong recommendation for all iOS users, is to empty their App Switcher
daily and perform a power cycle immediately there after.
This has kept my iPhone and iPad running smoothly ever since the first
stuttering symptoms appeared.
In addition, as a system admin I also hold to David's assertion that there
is a possible chance of corruption by performing the forced collapsing of
the iOS platform resulting from the 5 successive presses of the power key.
The iOS device at this time is not expecting this crash and as a result
maybe accessing a key string of code, or a significant part of your user
data. If this happened at the exact moment you performed the 5 successive
presses of the power key, it is conceivable that it might corrupt data.
The 12 second or however long it is, press of power and home at the same
time, is far more logical and sensible. As it is coded into the iOS as a
sort of… I want to reboot this device, prepare for it please and stop doing
anything critical notification to the device.
