iPhone 3G w/ OS 3.1 - Problems (Slow operation)

Here is an update on my situation. I originally began this thread early last week: http://discussions.apple.com/thread.jspa?threadID=2151711

1. My iPhone 3G 16GB was operationally flawless with 3.0.1.
2. I updated to 3.1 immediately upon it's release.
3. Upon it's first restart post-update, the phone was stalling during almost all operations. Sometimes for a few moments, sometimes for up to 30-40 seconds.
4. I tried uninstalling apps, turning off Wi-Fi, turning off Bluetooth, turning off Push, turning off MobileMe, etc. No joy.
5. After 2 hours of frustration, performed a "Restore" using my previous backup. No joy.
6. Performed a "Restore" as a new phone with 3.1, losing my settings, but having a fresh install.
7. Worked flawlessly.
8. Started installing apps and testing along the way. Still flawless.
9. The phone worked flawlessly for about 3 days.
10. Slowly started experiencing sluggish behavior again over the last 2-3 days.
11. The phone has magically restarted twice.
12. A few times a day, it will stall and behave sluggish for a few minutes, then recover.

Oh, and this is a new phone. In-between updating to 3.1 last week and now, I had a crack up the back of my case and Apple replaced the phone for free.

Also, all iPhone's have and will behave sluggish in low memory situations. Apple changed the way memory is dealt with in 3.1. (Apple removed all App Store apps that allowed memory alteration). I've seen it previously in 3.0 and 3.0.1 with certain games, etc.

So, my diagnosis:

This is not a hardware problem. I feel with a certain combination of settings, *the phone stops properly allocating memory and becomes sluggish*. I'm leaning toward MobileMe as the ultimate culprit, but that's a gut shot.

Apple isn't going to respond here. This is a public forum. Let's hope Apple has at least read these posts and is working hard on a fix.

Aside from crashing during the upgrade (requiring a factory restore then upgrade) my iPhone 3G (16 GB) has also slowed to a crawl. Applications load slower; whenever I need to enter text in an app, it takes up to 15 seconds for a key press to register on screen. This is unbearable. I wish I had never upgraded. Does anyone know how to downgrade back to 3.01? I feel like I just installed Vista on my iPhone.

I posted this in a couple of other threads: Yet another possible fix? I have also been having problems with very sluggish response and rapid battery drain since the 3.1 update. Due to this, my battery completely ran down last night. This morning, after charging and restarting the phone, it seems to be working really well! So maybe a solution is to completely drain the phone's battery? I'll report back if there is any change.

I don't follow, why wouldn't Apple respond to an important issue that's clearly affecting a lot of people across their own public forums. Other companies have this good communication thing going with their communities, why should Apple be any different. I personally think it's poor form and wouldn't accept a lack of response as anything short of unacceptable and unprofessional.

I have same problem too. When i upgraded my iphone from 3.0.1 to 3.1 all problem started. Last 1 day my iphone locked 5 times and i can open my iphone with press home button and top button 5 second. Please help because i can't understand that my iphone runs or not so every one minute i need to check my iphone.

Thanks...

Nothing new to add to the past 6 pages except to say I'm seeing the same problems most others have, all within minutes of upgrading to 3.1.

Have just shut off mobileme syncing, so far so good, but it's only been 10 minutes. Not happy. my $150 family pack renewal is coming due soon, having some real second thoughts if this isn't resolved quickly...

After posting about my problems I tried to see if my wife's iPhone worked any better. My wife actually told me she is experiencing random shutdowns on her iPhone. Or maybe is there a problem with some sort of crashes.
The phone takes a break from time to time and refuses to turn on or react to any button press. After a couple of minutes it simply reboots.
Before 3.1 her phone was terribly slow sometimes simply hanging during sync. She took the habit of plugging it into the wall charger to avoid syncing.
We bought our iPhones in the same place. So it might be an hardware issue on a batch. Or maybe Apple getting lazy with the 3G to push people to buy another handset.

Looks like quite a few new members with <5 posts so far signing up to report on this matter recently, including myself.

If you're lurking in this thread and are having the same problems the rest of us are, *please sign up and let Apple hear your complaint*. They need to know these are not all isolated cases caused by random app bugs, etc. -- this is a much bigger 3.1 OS problem.

Hi All

same problem here, experience strange behaviour since upgrade to 3.1
iphone 3G wakes up slowly, does not respond to a swipe.
wished to go back to previous version, the extra functions in the upgrade where hard to find anyway !
best regards Michiel

Well since I have upgraded to 3.1, my 3g has been doing the following
1. Shutting down randomly. Sometimes when I put the headphones in. Sometimes doing nothing. And has done so about 5 times a day on average
2. Battery life has shortened extremely
3. 3G network seems to go in and out as it pleases.
4. the actual Headset on the phone stops working every so often. No sound. Speaker phone will wokr.

My iPhone 3G was bought in Dec last year and has never been dropped, kicked, punted, or even harshly looked at. I've kept it cool and cared for it. It has been working wonderfully except till the day I updated.
So really. What is going on.
I almost got fired from work cause this turned off and I missed an important phone call.

I updated two days ago and am experiencing many of the same slow operation problems as most of you. I dont even run/use mobile me so how do I fix my problems?

Yesterday I started syncing my phone a 9pm.

It still hadn't finished when I was ready for bed so I left it overnight.

At 6.30am it was still not backed up, the indicator bar in iTunes was at less than 50%!

Tonight I'm backing up as I type. I started about 8pm and right now at 10.44pm it's at less than 10%

I just spoke with Apple customer service. Angie was her name (case # 136386406) and she said she hasn't heard anything about this. Hilarious.

Yup. Same problem here. Anyone find a way to downgrade back to 3.0.1?

Same problem here using an iPhone 3GS. Well described sequence; I've had essentially the same experience and came to the same conclusion (memory leak in v3.1). Apple, please work on this, as well as provide roll-backs in the future (e.g. to a more stable version, like v3.0.1 in this case).
