This is possible on the 3G but I believe (not 100 percent sure) it
only backs the OS layer and not the baseband.
The baseband is responsible for battery consumption and control. I've
heard the baseband is the issue not the actual 3.1 OS.
You can put the phone into DFU restore and hit the baeband level (in
fact you must), a regular (iTunes restore) only upgrades or refreshes
the OS if you restore to current version. DFU forces OS and baseband.
And no, DFU is not a hack or work around, it is the way to totally
restore your iPhone at OS and baseband level.
If you ever jailbreak your iPhone (which I do not condone or
recommend), if you ever wanna totally get rid of the jailbreak you
MUST DFU restore as a regular restore will replace the OS but leave
the modifies baseband which causes slowness and terrible battery life.

Dave,
My experiences are that I was able to restore the iPhone 3G but not
the GS series. If you need a good video clip to show you how check
"downgrade from 3.1 to 3.0" on YouTube. Follow these instructions
and it works perfectly. Also, if you need to carrier settings for
MMS, I can forward them to you.

iTunes should be keeping backups for you (they contain your
settings) as well as your music, ringtones, and apps. If so,
TimeMachine does keep backups. I know because I had to go into
TimeMachine to restore my settings from a previous backup to get
all my Cydia apps back (which had been backed up with AptBackup).
Your best bet though is to probably do a restore (I'd recommend to
3.0.1), and then have iTunes resync to add back in your apps,
ringtones, photos, contacts, and calendars. After doing a restore,
you can then decide if you want the carrier update or not.

Rats. I spoke too soon. Last night I applied the AT&T update to
activate the MMS function, and now it's no email time, just the
spinning wheel. Mail before the update, no email after the update.
I don't know of any way to 'de-update' the phone. I wish there was
a way for Time Machine to preserve the contents and settings of
the phone - now that'd be a feature.

I'm doing a slightly different experiment. I set the phone (3G) to
call forwarding to another mobile phone, but 3G connectivity is
otherwise intact. Mail, web, and GPS all function normally, and
I've stopped looking at the unending "connecting" message when
getting mail, because it appears to connect and get mail just fine
in spite of that. I'm now on my second day without recharging, the
phone hasn't been powered down, and I've still about 2/3 battery
life left. Based on this observation, it's the phone function
that's really pulling down the juice.
