My 3G (w/ the 4 GM) routinely freezes to the point where it just stops responding to input. I'll probably attempt to downgrade it to 3 soon. Which, I honestly don't mind. I mean, I would rather Apple not even support the 3G with iOS 4 rather than have to deal with this user experience. It's not like it can even deal with background tasks anyway...

Interesting, my 3G had the exact same problems as you (just froze and didn't respond to anything for like minutes at a time) with OS 3. But the problems have gotten a lot less frequent with OS 4 for me.

I read somewhere that upgrading a 3G from OS 2.x to one of the OS 3.0 betas and then to OS 3.0 final, without doing a full reset somewhere in between would cause this problem. OS 3.0 was sluggish as hell for me until OS 4.0 beta came out and I did a full reset. I'd get random pauses and freezes just like others here are reporting. After the full reset, the 3G was running smoothly again. I just upgraded to 4.0 final and it is smooth too.

A full reset kind of sucks. We're not talking a restore here. Just start from scratch. With the exception of one or two apps though, my data was in the cloud so it was largely painless to get everything back in sync.

It's worth mentioning that when you do an upgrade, the Spotlight process must go out and re-index all of the content on your phone. This is a background process that might take a few hours to complete, especially if you have a lot of content and email. Most people are saying that after a few hours the phone is noticeably faster or at least back to normal. I think what is happening here is this background Spotlight in…

The moment after I upgraded, the phone was completely useless. I restarted twice and it picked up a little speed. Its now 24hours later and its still extremely slow and laggy.

I've always found that for some reason with OSX (which is perhaps somewhat comparable), I get the best results with a fresh install. I think Apple sometimes doesn't do the best housekeeping.

now to see how many people will downgrade to ios 3 instead of being persuaded to upgrade to the iphone 4...

None. This Guy was literally "thanking the apple gods" for selling him a new phone after basically bricking his old one.

Apple has never cared about supporting old hardware and they never will as long as people are falling over themselves to shell out every other year.

Yeah, just download your firmware from this page, then option-click Restore in iTunes and select the IPSW. http://www.felixbruns.de/iPod/firmware/

Didn't work. Restore failed. Trying to restore to iOS4 now.

Really? What was the error?

Got it working. I followed the instructions and got stuck with error 1015.

I had to do two things.

1. Switch of your iPhone and put it in DFU mode with following instructions - Click the Home + Power On button for 10 seconds exactly - Release the power button and continue to click on Home

2. Restore and it fails with Error 1015.

3. Run iRecovery -s followed by fsboot, following http://www.ihackintosh.com/2009/09/recover-iphone-3gs-from-a...

I am back with 3.3.1 Thanks a lot guys.
