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.

Seriously. Try restoring as a new iPhone and then restoring from your backup. It worked for me. My iPhone 3G with os4.02 works great, so should yours.



So...your 3G iPhone is working perfectly now under ios4.02... Highdef ..... or should I say... (reaches across and yanks off rubber mask in true Scooby Doo style) ... +'Mr. Jobs'+... DA-DA-DAAAAAN!

I juts downgraded my partners phone to ver 3.1 and I am keeping mine with IOS4.0.2. The difference in speed is impressive. I will be doing a comparison (hopefully tomorrow).

The only reason that I have not downgraded my Iphone 3G is because I have a lot of work stuff on it and dont want to risk loosing everything. Much rather Apple helped us a bit on this.

An update...

I made a genius bar appointment for my iPhone. They tried a few things, then they replaced my phone (even though it was out of warranty).

I now have all the functionality of my 3G with none of the hassles of the new operating system (I'm back on the OS 3.1.3). They apologized for the hassle and I'll be upgrading my phone to the iPhone 4 in the next few months.

The service and response at the store kept me as a customer.

Thanks Apple! Own 2 ipods, 2 iphones (3G), a macbook! Just spent 3 hours of my life downgrading to 3.1.3. See if I purchase another apple product. Now I reverted back to 3.1.3, 1/2 my songs I bought are gone, and I had to re-install all my apps. The phone is back to its normal speed. 4.0 *****! Bogged mine and my wifes phones down like no other. At least I can use my phone again. **** poor quality and shame on YOU.

Another brilliant plan to get attention in the media.
The more we care, the more they sell, it always happens.
Just take a close look at "Apple Computer " history.
We buy, then we pay for it "later", with product and software beta testing.
The Apple customer is the test lab, and we willingly participate... cautiously.

Did Apple write the new code to work with the new Iphone 4? They also needed to get the new iphone Manufactured to mirror the ipad, so is anyone really surprised the old iphone 3g could not run the new code, "efficiently"? It is kinda like running leopard on a g3 laptop, prolly not gonna happen. So now Apple has to write new code for both phones. I am sure it is possible, but does not sound very easy to do.

I entered an Apple store in Colorado today and the employee there had no clue about what I was talking about, (3g iphone) problems, and also had no idea there was an issue with the software.

That pretty much raps it up for my confidence in Apples customer service skills. It reminds me, of the concept, of an un-nova. it slowly consumes itself until it disappears.

I'm not saying my iPhone is running faster because of 4.0.2. In fact I never had 4.0.1. Because I installed as a new is what's making it much faster. It wouldnt matter anyway since the OS was wiped out upon taking it back to "newness".

I measure the speed by how long it takes the keyboard to respond to my typing. The response is instantanious. There are no pauses between letters or pauses navigating between emails as before. How many times do you have to press one of the "back" buttons before the device actually acknowledges your request? (i.e Inbox, Messages, Edit, etc.) I press once and instantly the button darkens for not even a half second then executes.

BTW - I still have all of my apps.

Hello:

Do a little research.

There are ways to go back. I did it last night and love my 3G iPhone again!

It is not that difficult, does not require a JB and worth it. You have to reset a few things here and there but it only took an hour or two. OS4 caused all kinds of problems on my 3G iPhone and yesterday was locking up, crashing and causing tremendous difficulty. I figured if I have to do a restore anyway....might as well go back to what I liked.

Now it is back to the way I remember. I never updated my wife's 3G phone to OS4 and won't unless this community is happy with a release.

Good luck

I just hated the OS4 upgrade to the core. My battery drains in a few hours. Texting while listening to music was a dud.
The iphone OS4 doesnt improve the performance one bit. I decided to roll back to 3.1.3 and was successful in doing so. Thank you apple for making things miserable for a couple of months. I can live without folders and playlists compared to the speed of 3.1.3

I really liked my IPhone 3g when I first got it. I was impressed with the apple os so much that I was considering changing my desktop to apple. I now have reconsidered. Putting out an os that is not really backward compatable and telling customers that they should update through itunes is a bad idea. I now dislike the phone and there seems to be no going back to an os that works. Apple should give 3g owners a discount on a phone that works with thier current os or many of us will be headed to droid land. If they fix ios4 so it works with the 3g great but it will not compensate for the months of crappy phone function on a phone I cannot get rid of because of a 2 year contract. It says to me that apple cares very little for it's customers if they cannot run out and buy a new phone to run the latest and greatest new software. There could not have been much testing on the older phones. It is not a real hard to see problem.

this is affecting almost all 3G users - I was out last night @ an annual football pool and every 3G user (including myself) in the room are having the same issues. the phone has slowed so much several applications are now useless and everything from sending texts to receiving calls has dramatically slowed.

the ONLY way Apple will respond is if enough media gets involved the stock starts to react negatively so instead of wasting your time on this blog email/call/write your local (preferably national) journalists to start writing on the subject. eventually the business journalists will catch on and that may get Apple's attention...

Okay, I just read on the web about Apple's announcement of IOS 4.1 to be released next week. This update is supposed to fix the 3G bugs. So why, when I just spoke with Apple Technical Support, didn't she tell me that? She obviously didn't have a clue either. Goodness gracious, I hope that level of knowledge from the Apple people isn't indicative of what we'll get with the update!!

I've been reading through this topic since updating my iPhone 3G to the new software, and I just wanted to share my feedback that I just sent to Apple. Sorry, it's kind of long:


Dear Apple,

A month or so ago I updated my iOS software on my 3G iPhone as prompted by iTunes. I did this because it was billed as an "update." I have had no problems with any other updates offered by Apple on my iPhone, iPod or 5 year old MacBookPro.

However, since downloading the 4.0 "update," my phone has been unbearably slow. Applications shut down unexpectedly or refuse to open at all and it often takes 10-20 seconds to open MMS, the Internet or other standard features on the phone.

I know from doing some research online that this has been a common experience for 3G iPhone users when they update to the new operating system. I am sure that your company is aware of the problem.

But what troubles me is your response to this problem. As far as I can tell the "official" Apple response has been to deny the severity of the change in phone performance or to suggest buying the new iPhone 4. Basically you are not being honest with your loyal customers about the problem and/or deliberately tampering with their Apple products to force them to buy the newest hardware.

Either way, I'm disappointed, and I'm not alone. The tone of formerly avid Apple consumers online is of frustration and anger.

Customer service and quality of products is what has set Apple apart from its competition over the past ten years. It's what Apple is built upon, and what made me personally a complete convert to Apple products. The recent performance issues with my phone and the subsequent response by your company has not made me want to go buy the new iPhone 4. On the contrary, it has made me seriously consider switching to a competitor.

My (and I think most 3G users) request is simple. Let me go back to the 3.1 iOS. The 4.0 software is too much for the 3G. Fine. I get it. Then don't tell me it is an update for my phone; and at least give me the option to return to the old operating system. I know I can do this manually. But why should I spend my time and my energy fixing your mistakes?

I've taken the time to write this email not because I expect any response in return. But because I have been so pleased with your products and service over the past 7 years and I wanted to express my concern for the direction of your company. I hope that you will honestly address this problem soon and offer your customers a viable solution.

Thank you for taking the time to read this comment,
My Name

PS- I have tried the solutions offered by other users online, such as doing two hard resets, turning off all spotlight searches or turning off MMS altogether. These options give only temporary, minimal performance improvements (resets, turning off spotlight) or completely negate the point of having a cellphone.
