Slow iPhone 3G after iOS 4

I downloaded iOS4 for my 3G and instantly noticed a performance degradation. Considering the iPhone is a "work" tool as much as being a phone, I can't afford to have it not working correctly. I checked around in the support area here and the common theme was to reinstall OS4, not as an "upgrade" but as a fresh install. So I did that last night. The slowness, and I'm talking 8-10 seconds for a text to appear after I clicked "view." That's unacceptable. Maps were equally slow. So in consideration of upgrading and reinstalling OS4 - AND doing the reset (there is no hard reset) it's still slow. That being said, I would imagine Apple is feverishly working on an upgrade to fix this and other issues. However, until that upgrade comes out - and has been out, I'm going to do whatever I need to do to "go back" to iOS3...

Your thinking is logical and correct when you say.. "does OS X run as good on a Core Solo chip as it does on a Core 2 Duo? Of course not - it runs, but not nearly as well." I agree, but...if a single core chip gets OS X installed there should be, and is, a way to revert back to the OS that is more efficient. This should be the case for the iphone as well. Couldn't Apple give us the full disclaminer before having us install 4.0 on a 3G iphone. When attaching to itunes it simply says... there is an update for your iphone and then you essentially get the equivalent of OS X on your single core chip when you would prefer to have kept the faster, more efficient OS and not the one that slowed you down for the sake of some insignificant upgrades like folders and a camera zoom. In my opinion 4.0 should not have been an officially released upgrade, by Apple, for the 3G iphone.

Yes Thank you for stating the obvious!

It is Apple's responsibility to state what OS is best for the hardware you have purchased and to NOT release official updates for your hardware that reduce the performance and/or functionality with no explaination other than "your iphone software has an update". This is the issue! Upgrades that reduce the function and/or performance of the hardware should not be called "upgrades" and should at the very least bear "warnings" of the symptoms you might experience by installing it. THUS they should be OPTIONAL and not simply identified as an update. The "OS 4 update" on the 3G iphone is like Microsoft telling you that there is an upgrade to your XP software and when you click 'install' you get Vista on your Pentium-233 processor! It's just not right.

Tried all the above. What seems to have helped the most is killing Safari. iCal was the most affected by speed. I switched off all of my subscribed calendars and that seems to get it back to barely usable vs. completely unusable (literally 2.5 minutes before it responded to input). Although not having the various holiday and sports team calendars is rather annoying.

I tend to agree that it's simply an available memory issue. Just not enough left over after iOS4 gets done. However, that also means its something Apple can correct for the 3G since its a software optimization issue (I guess they could just as easily give ical and safari smaller footprints as they could do a "3g-only" build of iOS4). Whether they will or not probably depends on how much of a continuing stink we users make. After all, the point was made that Apple continued making the 3G available for sale up until a few weeks ago. I could see if it had been a year...

So here's hoping for a quick and effective 4.01. And I will wait on purchasing the new phone until they've worked out the x.0 bugs. I'm pretty sure that's why the white version was further delayed. I would bet it will incorporate some internal fixes.

Yes Thank you namedome for stating the obvious!

Remember, not everyone out there is jail-breaking their iPhone and trying to turn their 3G into an iPhone 4. We just want the best software that is officially available for our device.

I like your example about Vista on an XP machine. The "OS 4 update" on the 3G iphone is like Microsoft telling you that there is an upgrade to your XP software and when you click 'install' you get Vista on your Pentium-233 processor! It's just not right.

Indeed, dude. I'll wait a bit for my iPhone 4 until they fix what they need to fix. In the meantime, I'll pray for a 4.01 update for my garbage 3G.

I second that... but more, 1) the "Upgrade" should be an integral option... meaning one you can decline without constantly being reminded that an "Upgrade" is available.. 2) A revert option should be available if you decide you don't want it. For example, when upgrading your Apple computer to OS 9 years ago, if you didn't like it, you could simply reinstall OS 8 and keep going... this doesn't exist with the iPhone... there is no previous OS to reinstall... you'll have to go the hack route to do that.. 3) if the potential for a negative operational impact exists because of an incorporation of advanced technology vs older technology, then a disclaimer should be applied... just my 17 cents... but I'm punchy because I'm tired of fooling around with the phone...

First of all, sorry for my english level.

It is very frustating to pay for a tool like iPhone and see Apple make it a garbage. We are never able to obtain any answer or services.

We all know that the goal is to sell us a new model.

Some advise MUST be state to user before forcing update.

Can we start a requst in a group and act together ?

If everyone here complains, maybe something will be done! Send your complaints to Apple rather than this discussion board:

http://www.apple.com/feedback/iphone.html

Tell Apple you're angry!

I have submitted feedback to Apple, on the feedback website. I also called customer support. I urge all those having problems to do the same, but to keep posting too.

Hey Greg, i tried going to the link you attached but comes up with error you don't have permission to enter (or something like!), have apple blocked it or am i doing something wrong?

I have many of those symptoms, plese Apple let us restore to previous OS3.

Try the App Freememory. I think I have good results with regularly running this App. It has a new version for iOS4.
I am not the developer 😉

My iPhone 3g is wildly slow after doing all of the recommended fixes. I have given up on using the map entirely, the camera loads so slowly I inevitably miss whatever I'm trying to shoot.

I'm getting pretty used to this level of Apple sloppiness.

How long until Apple release an iPhone 3G fix for the slow IOS4 on 3G's.


SOOOOOOOOOOOOOOOOOOO ANNNNNNNGGGGGGGGGGGRRRRRRRRRRRRRRYYYYYYYYY
