Slow iPhone 3G after iOS 4

great tip. that makes a lot of sense, and I will be sure to try it.

I know this is a stretch do you know if there is any place within a Mac where I might be able to retrieve an older phone backup? I know sometimes data still lives somewhere, but don't have enough depth on a Mac and or iTunes to know if this is possible.

Ancient Artist, if you sync your iPhone with your computer, then all your data is safe. You just need to invest a little time on repopulating your iPhone with your data and forget about the backup part. It really helps making your 3G "faster" again. But I'm not saying it doesn't slow it down. It really does. Some days runs fine, some days is garbage.

again..... my iPhone 3G is garbage after iOS4. Did restore as new phone, but after a couple days, back to garbage. Even typing text messages is annoying. Delays on the characters,...

This is one of the most annoying issues. I can actually get way ahead of the display when I am typing.

This is a very disappointing experience, but the silence, from Apple, is even more frustrating!

The hard restart (holding home+power until it restarts, past the slider) improved the situation for me.

Regardless, I wish Apple would make it possible to downgrade to a previous OS. It's totally ridiculous that I have that little control over MY OWN TELEPHONE.

Yeah, I guess I'm not going to get this new iPhone after all.

I haven't had any apps crash on me yet, but there's definitely a visible lag - especially in changing orientation and keyboard input. Otherwise (opening apps/folders etc.) seems to be working fine. Still, it's frustrating.

Hi Greg, I tried going to this forum and I get error msg that I am not authorised to enter this forum. What kind of id is needed?

I want to downgrade as my iPhone has become very slow after ioS4 upgrade and I want to go back to 3.1.3.

My phone and all apps were working Great. After OS4 my phone is slower on everything! The biggest thing for me is now I can't use the last.fm or pandora apps. The first few songs play, then the songs start skipping like an old cd, or the app just crashes, or my phone freezes. I have restored my phone, and have deleted the apps from the phone and itunes, and reinstalled. Still same crappy result. I did also call the apple help # yesterday, and was told yes the OS4 does not work well with 3G, but there is no fix. Can we get the old OS back? Thankfully my 2-year contract ends in two months -- many more choices out there now with no ATT attached.

Apple, what are you doing to your loyal customers. If you recently got a 3G and upgraded to the iOS 4 software, your 3G is borderline useless. It has been made unaffordable to break contract and purchase the new phone. I have called Apple Support 2 times and they are "well aware of the issue". However, your site still says it is compatible with the 3G. WTH?

You owe your customers an update to our now useless 3G phones.

Is something in the works?

Please help!

My experience is similar to the majority of posts here. I find that over time performance is slowing to a crawl (unusable), so I'm forced to reboot my iPhone daily, otherwise it gets to a point where I can't even answer a call because there is a delayed reaction to touch! I'm hoping apple recognizes this is a major pain for 3g users and issues a new update asap.

Upgraded my wifes 3G to 4.0 and have had nothing but problems since. I have restored as a new phone and hard reset the thing until my fingers were numb. Slight increases in speed can be had but they are all temporary. If we don't have an update or word on a fix soon I suppose I'll have to manually take it back a version. Pretty sad when we have to resort to downgrading ourselves after Apple rendered the perfectly capable 3G useless and slow.

Thanks Apple.

I had this issue and it turned out to be a corrupt download of iOS 4. Delete the file (C:\Users\XXXXX\AppData\Roaming\Apple Computer\iTunes\iPhone Software Updates) and redownload.

I had all the problems over slowness and battery life that people here have complained about and did the restore as new phone, hard resets etc. What did eventually work although I can't be sure as I tried so much, was a Reset all Settings and letting the battery drain till the phone switched off and leaving it to recharge fully before using it again. I've had it on standby for 2 days 3 hours now with 4 1/4 hours usage and it still hasn't dropped to 20%.

That's probably low usage by most people's standards and admittedly it's been mostly on wifi in that time but there's no doubt it's a huge improvement on its recent performance.

I upgraded to IOS 4 and I have also been experiencing extremely slow applications or just non-respondant screens. It has become very difficult to type due to this.

OS4 completely bloody useless - slow, aps dont work, battery drains faster than a keg at a college dorm party.
For those of us not willing to "upgrade" to the iphone4, Apple, please give us a downgrade path back to our old os3

I'll simply do a +1. My 3G under iOS4 isn't unuseable but it is frustrating at times when it seems to go off thinking about something else.
