iPhone firmware update 3.1.2 is out! How's it working for you?

Whew relief at last! but 'your mileage may vary'. I am very curious how well it's working. I really hope 'comatose' is a word we can quickly forget.

I was at 3.1 last night and had hopefully my last coma ever. I put on 3.1.2 and it went very smoothly other than for some reason some of my apps lost their data. (i lost hundreds of entries from my 'Lose-it' weight management program (AWESOME by the way; down almost 20# since July).

Since putting on 3.1.2, however, phone not quite as responsive as yesterday on 3.1 (something i can deal with if it never 'goes coma' again), but once in a while it's a pretty long pause, like a 4 sec. pause in the middle of a tapping a word; again if it's a trade-off to have the phone work 100% of the time i can cope with that.

Anybody that does try the upgrade and has a problem, please go through the normal steps of putting on a clean install before 'going ballistic'. Basically, i would recommend doing a backup, putting the phone into DFU BEFORE the first attempt of 3.1.2 (which i didn't do... could be related to the 'stutters' i'm getting right now).

I recommend this method:

1. backup your phone manually (in case it doesn't ask) -> right-click on phone and pick backup
2. Get your phone into DFU mode (search apple help or google; you-tube is has great guides)
3. restore the phone while in DFU. In my experience, the phone is dark while DFU restore
4. activate the phone and 'play around a bit'; i use m.me so i can have my contacts back w/o sync
5. if things are not going well, i would go back to step 2 and re-install
6. test drive for at least a few hours before doing a 1-hr restore from backup (of your data).
7. come back here and give some feedback if it's working (or not).

So.. for me, the summary is: super-smooth 'restore' to 3.1.2 but like a 'moron' (don't take offense, it's a term of endearment for a smart person that doesn't do something the best way by being hasty).. i did just a direct upgrade from iTunes w/o heeding my own advice and DFU the phone first.

So.. i have had a couple instances of 'non response' to things like hitting the home button, the sleep button, but i've had that since 3.0; it was why i upgraded to 3.1 in the first place. I'm very curious about why my 'accidental' install of 3.1 was so darn fast, and i want it back, so over the weekend i'll do a DFU re-install of 3.1.2 if it doesn't clear up with a restart.

No coma yet, but too soon to know if 3.1.2 is the reason. If you have a perfectly working phone at 3.0 or 3.01, i wouldn't bother upgrading, the only 'super cool' thing you'll be missing is the ability to sort your home pages icons in iTunes (super amazing; best part of 3.1 OS for sure). Just wait a week or three to see what others say first!

Oh.. if you really want a clean install.. use a fresh 'user' on your computer to do the update, then just don't bother syncing, and switch back to 'you' before doing 'restore from backup'.

Ok, wish you guys all luck, hope that everybody has a fully operational phone/ipod after this.

All the original apps the came withe the phone work, even tried installing new app but it won't open either, I read about everyone else's problems no one seems to be having this problem, I am afraid to upgrade my phone still running 3.1.0 with no problems. Anyone help me

upgraded to 3.1.2 a couple of days ago - upgrade went smoothly - did a discharge/recharge to recalibrate the battery - never was on 3.1 but on 3.01 10% if the battery was 25-30 minutes of use with wifi - on 3.1.2 after the calibration 10% of the battery is 45-48 minute use with wifi - at least so far

no other issues - since i never went to 3.1 i never experienced any of the problems reported with it

Just a comment, I thought the dropped calls I have had all weekend were a result of the upgrade. Then I restarted my 3G iPhone, I was able to send a text message and call my voice mail service at the office. Then I received a call and it was dropped AGAIN. Finally I realized it had to be AT&T dropping the calls and in spite of spending a half hour waiting on my land line phone to talk to a tech, the call was disconnected. Now my iPhone it is working off and on, in spite of the bars showing a good connection. I have one more month to qualify for the 3GS upgrade, hope I have service before then.

I installed 3.1.2 right away when it arrived 10 days ago. It ran very well for about 8 days. The last 2 days it first became sticky and calls were dropped... directly after the coma modus came back.

Seems to me some file gets damaged and the sleep/wake instructions are not loaded correctly.

Apple needs to resolve this issue with the highest priority possible.

In the mean time I am desperate to downgrade to 3.0.1 but Apple does not allow it. I feel like a prisonor of my own device.

OS 3.1.2 did NOT repair the coma probmem. It is also slow and sticky.

I cannot put my iPhone to sleep because in most cases it won't respond to any button, no matter how long you hold them down, either simultaneously, or separate: my iPhone does not respond, its in DEEP COMA.

In most cases my iPhone only wakes up after connecting it to the charger.

Once connected to the charger my iPhone works completely normal. The lengt of the charger cable however does seriously restrict my mobility 😉 In fact my iPhone turned into a old fashioned land line phone...

I REGRET SO MUCH heaving been such an early adopter of 3.1 because that's where the coma problem started.

With 3.1 and 3.1.2 my iPhone became practically usless. Apple PLEASE, PLEASE, PLEASE tackle the coma problem!!!!
