Iphone 3G slow after update to IOS4

The upgrade to IOS4 took forever but eventualy was completed succesfully.
But the iphone is very slow with IOS4. It doesn't work as smooth as it used to be. Also new applications such as the iBook application are very slow, doesn't respond smooth on screentaps etc. Who has the same experience?
I'm thinking about going back to version 3.1.3 because IOS4 doesn't add anything to improve the user experience on the iPhone 3G.

I hope Apple will listen to their iphone users and will release an update soon for iOS4 which improves the performance on older iPhones.

Iphone 3G, iOS 4

Irons you can try this "magical" process to get to 3.1.3 again, just takes a few steps to follow closely but yes you can.

For both PC and MAC:

I just downgraded my 3G from 4.0 to 3.1.3 and it works just as before. Familiar icons, speed is back. Just pay attention to all the steps as there are unique files for 3G versus the 3GS model, each of which are listed there.

Just got off the phone with Apple support. I am very unhappy. After I upgraded my iPhone 3G to IOS4 it became completely unusable. Apps crashed and hung up. The phone was VERY SLOW!!!! Songs and podcasts would stutter and stop during playback.

I updated to 4.1 hoping that would help, but it didn't.

I can't live without my phone. I use it all day for navigating, music and podcast playback, email, web surfing, and (gasp) to make calls. I had been a HUGE fan of the iPhone, and have personally convinced a few people to buy them (and unfortunately they upgraded too).

Because I need my phone to actually work, I downgraded to 3.1.3 and was forced to jailbreak, because apple offers NO way to officially downgrade. because the modem firmware got upgraded during the OS update, iTunes won't let you downgrade to an older version. UGH!

Now, my phone is much more stable, but it still isn't working correctly. I can't connect to YouTube using the official YouTube app, and some other apps don't work properly.

I JUST WANT MY OLD WORKING IPHONE BACK!!!!

I called Apple support and was told there is no way to downgrade (officially), and BECAUSE I JAILBROKE MY PHONE, MY WARRANTEE IS VOID!!!! Very bad service! Apple's software and firmware update BROKE MY PHONE, and they can't or won't fix it, and the only fix VOIDS MY WARRANTEE!!!

I feel like Apple is trying to force me to upgrade my hardware by breaking my good, working iphone 3G, which isn't even two years old. I can't even express how frustrated I am, and this is coming from a true Apple fan. I have owned 9 or 10 Macs, starting with a PowerMac 7200, and including a Cube. I have purchase 2 iPods, an iPhone, and countless accessories and software upgrades. More than that, I have encouraged a ton of people to buy Macs and iPhones, and because of my position and knowledge, they have. Now, I feel betrayed.

PLEASE FIX THIS APPLE!!!! I WANT MY PHONE BACK!

After updating iPhone 3G to ios4.0.1: apps crash, battery life is shortened, typing is delayed, Internet connections are painfully slow, iPhone gets hot, lost visual voicemail for a week, AT&T said my best option is to buy a 3GS because the 3G is just not compatable with new ios4. Apple needs to provide free fix for these issues - I've paid enough for this phone, which until upgrading to 4.0 (which in itself was a slow and painful process and 4.0.1 did nothing to remedy any of the issues) was a fine phone and my affection and enthusiasm for Apple was intact, but now, frustration prevails.

I think Apple need a good kick in the backside. I've had my iphone 3g for over a year now and it has been brilliant until iOS4. Everthing worked flawlessly.

1. If the phone is locked 4 times out of 10 it will not respond. The thing that you slide then sometimes doesnt even know your sliding it. Putting the password in is a complete fail. It can take 5-10 seconds for a letter to appear.

This means that if i need to unlock my phone it can take me 30-40 seconds. In my opinion that is NOT GOOD ENOUGH!

2. Messaging has become terrible. If i press the messages app it takes 6-7 seconds just to display my messages. Then a further 10 seconds to even attempt to type a message out.

3. The calendar has slowed right down. To switch months i have to press the arrows several times for it to recognise that ive been pushing it.

4. The camera takes an age to load up and take pictures. I wanted that shot 10 seconds ago. Not now. 🙂

5. Contacts isnt instant. Still takes several seconds.

There are many more problems that EVERYONE is aware of. I have another 10 months on my contract left (Im on a 24 month contract). I spoke to O2 and to actually get out of my contract it will cost me £350+ and then if i wanted an Iphone 4 a further £370 to take the phone out. This phone is suppose to be getting better and better and better. Unfortunately not. For me with every update it is getting progressively worse.

I even decided i would downgrade to 3.1.3 and when i did none of the apps worked because they are only releasing apps for IOS4 now.

This is my 2nd post on this forum. My first post was about an ipad which i ended up getting banned for a few days off the forums. If i could speak my mind now i would be banned even longer.

Get it sorted Apple. We are giving you alot of ***** money!

For anyone wondering if this process works, the answer is "YES". If you follow the fairly simple directions step by step your unusable iPhone 3g with iOS4 will be downgraded to 3.1.3 and be usable again. You may lose some information that is stored in apps but most of your contact information, playlists, etc can be restored with a MobileMe sync or an iTunes sync. Try it, you'll like it.

I'm not sure what happened to Apple with iPhone, clearly they released software and hardware that has serious problems, problems they KNEW about before releasing (there is absolutely NO WAY the could not have known about these issues before release date). But as with many companies, release it first, fix it later. A very out dated business concept that just doesn't work in this day and age. People just aren't "accepting" serious problems like they used to -- the "new tech" of mobile devices is no longer new so problems just aren't acceptable any more.

Not sure what's going on with Flac, he/she seems very sensitive to criticism, no matter what one says they are "rude" in his/her world.

Good luck with getting Apple to say anything official, their standard approach to information release is via ADC or carefully leaked information in which they can then deny as "rumor or speculation" or not (if it suits their needs). Good example is OS4.1 Beta 3 -- it's ok to let out the information it "fixes" the 3G problem, but Apple can deny if they like -- gives them full flexibility.

But it appears they have lost A LOT of potential customers and existing upgrade customers because of all the issues. I was just at a Verizon store getting a Droid X activated, and she noticed my old 3G iPhone (EVO 4G is on order) and indicated she's had A LOT of now ex-iPhone customers and heard the "horror" stories.

Apple have released a new 12 core MacPro, so that's a big plus!! Not ALL bad at Apple.

Flac, you are correct. I just stuck to the facts of the case without deviation.
The facts in evidence are; iOS4.x is not compatible with 3g/3gs phones. There is no disputing this fact and I bet I can find a jury of 12 iPhone users (plus a few alternates) that will concur and rule iOS4 guilty!

My office mates also updated their 3g/3gs'(they are NOT on this forum) and they too are having the same issues I am. That's how this started with me... While at the water cooler, I said "are you guys noticing that after the update......." Everyone concurred. So I bet there is even a silent majority of iPhone users who are not speaking out about this issues.

As for switching to another company. Each person must make that decision for themselves. For me, I was able to roll back to 3.x and am quite happy. Don't fix what ain't broken. Also, very happy with my now 3 year old iMAC, my new Mac Book and 5 year old iMac G5.

As a Mac user for >15 years and iPhone user since day one...I must say that I am profoundly disappointed at almost all aspects of my 3G after "upgrading" to 4.0. I agree with the comment that it's just about only good for a phone these days. Patience is a virtue, but this is stupid! Almost everything crawls or worse. From the camera access time to SMS typing, this is about the worst I've ever seen an Apple product perform. Frankly I am surprised despite all the views on this post that more hasn't been done or more noise hasn't been made to get Steve & Co. focused on how many of his vast legions are disappointed beyond belief. Sure the 4G is sweet and but we 3G'ers are in a death-grip of our own with a really really slow OS4 plus our ATT coverage quality.

Folks at the Stores say 'yes, we know' and 'hang in there'. Clearly this OS4 on the 3G is a >death-grip quality issue. I hope the community will continue to pressure Apple to fix this problem ASAP.

I finally decided to create an account here -- just to add my opinion to this hot topic. I remember hearing Steve Jobs say that he likes hard numbers. Well Mr. Jobs, this topic is approaching a quarter of a million views -- and the problems are very real.

Fellow iPhone 3G users, consider this fact: Apple has made a WHOPPING 4 different models of the iPhone. (excluding storage capacity variations)

For that reason alone, you can't convince me that their "quality assurance" team wasn't aware that the iPhone 3G would slow to a crawl with the iOS 4.0 update.

What gets me is that to this day Apple is still encouraging 3G users to update to iOS 4. (and no official downgrade back to 3.1.3)

Oddly enough, my wife has an iPod touch that we purchased in mid-2008. She recently upgraded it to iOS 4 and it works great.

Considering that a good percentage of the iOS 4 improvements don't work on the 3G anyway, we would benefit from a stripped down version (like they did with the iPod Touch.)


My thought is that this is Apple's form of "Planned Obsolescence", since the 3G is already 2 years old (and most contracts will soon be up.) Apple (and AT&T) want you to get the newest iPhone -- and more importantly, commit for another 2 years with AT&T, as they will lose millions of customers when the iPhone becomes available on another carrier.

As for me, I upgraded alright. My personal cell is now a Droid X on Verizon. (I still have the iPhone 3G as a business cell.)

I finally decided to call Apple the other week and officially submitted a report with a senior advisor. Pretty much all he did was have me e-mail him a diagnostic report on my 3G.

He told me he would forward this information to the engineering department. Don't quote me on this, but from the way he was talking it sounded like there would be an update for the 3G to resolve this issue in September. I told him all would be forgiven if he would just send me a 3GS, but he wasn't having it!!!

At first I thought this would be resolved much quicker. Like someone said a few replies before me: its been 50 days since we have had to suffer with an excuse for a phone, let alone an iPhone.

If Apple would come out of the woodworks and publicly address the issue and admit fault, I would have an enormous amount of respect for them. Like Steve Jobs said in the last conferance: "We are not perfect".

We want this problem fixed and we want an apology.

I updated my phone to OS4.0.2. It is a bit faster, however, I downloaded first and then restored it as a new phone. I saved my contact on my pc address book and was able to transfer. The apps, photos, and music can be transfered with ITunes, except you will loose your text messages. You could buy a software or use this website. http://www.iphone-sms.com/
Good luck to all of US. I WILL WAIT TO SEE HOW HONORABLE THE APPLE COMPANY IS.

Apple's behaviour over this issue is outrageous and unacceptable. My use of my Apple product has been affected by a software update from apple installed without any warning of the consequence via itunes. No opportunity to roll back an OS which is presumeably designed for the more capable iphone4. Apple store techies just say sorry but tough - nothing can be done. Another instance of corporate arrogance or a cynical attempt to force us out to buy a new iphone. OS 4.02 is now released should I install or will it make things worse and why should i even have to ask? Who needs a virus when the company doe the job for you. Urgent action is required NOW

How about filming your Iphone or giving some timings from your supposedly corrected Iphone in order to give credibility to your claims.

I would say that your claims are overstated to say the least!!! yes a restore will help for a while it clears you phones memory. IOS4 in its present incarnation is simply too heavy for the processor and Ram and no amount of restoring will help that.
