what happens to those who have jailbroken with SpiritJB? i heard you get sent into a boot loop is this correct?

Nope.
I went from a Spirit 3.1.3 (whatever) to the GM and it just wipes out the phone as new.
When I went back to 3.1.3, it went into a loop which I was able to fix.
In other words, you shouldn't have an issue upgrading.
 
Find My iPhone has worked fine on the GM Seed for me on my 3GS.

Maybe I just need to reactivate Find My iPhone, or maybe MobileMe was having an issue, since it was about to be revamped when I tried it last.
 
Same build as the developers release!?

Oh man - people are going to be PISSED off when they see how poorly this thing runs on a 3g. Seriously. Prepare to reboot your phone every other day. Its a memory leaking _hog_.

It may not get any better for those not using an iPhone 4. Last year, when iOS 3 was released, it never quite ran right on the iPhone 3G and this was never quite fixed. While it clearly ran on the 3G, it became apparent that iOS 3 was optimized for the 3GS. For tose of you with 3GS's, let's hope Apple doesn't totally ignore you.
 
While the release share the same build number as the GM release one bug has been fixed. The default wallpapers was empty when running the GM release on the iPod Touch 3G, while on the release version all wallpapers are available.
 
One of my apps does have a couple new leaks introduced with the new API, but they are small. No, the phone became unresponsive after JUST using Apples own applications. Mail/Safari/MMS mostly.

You have a 3g and not a 3gs right? My 3gs seems to be a lot better off.

I'm on a 3GS. iOS4 does use a lot more ram, so its probably kicking the crap out of the 3G rigs.
 
Bricked

It just bricked my unjailbroken / un-moddified iphone 3GS. I have never installed any of the beta OS4s either.
 
My download completed in less than 2 minutes. Has yet to install on my iPod touch 2G though.

I do however find it hard to believe that Apple hasn't updated the iPod touch yet. Since the 8GB iPod touch they sell right now doesn't support all of the iOS4 features, I thought they'd for sure upgrade it. It doesn't seem like Apple to leave some of their products incompatible.
 
Slower?

Does it seem like it is making the 3GS kind of "jumpy?" The update makes it run slower and kind of reminds me of my Windows Mobile Phone years *shudder*

iOS 4 has been running fine for months on my 3Gs, and it definitely feels faster than 3.x, especially application launches.
 
I already have the GM, so I have the same version and build that you folks that are downloading have. No need for me to update.

Same buildnumber, yes, but not byte identical. Something has changed, and I'm not taking any chances, going to restore with the release version.

I have a 3G (not S) and never had any issues with the iOS 3 version. It worked as well if not better than the iOS 2 it came with.

Is it possible that your benchmarking tools may be what's causing the leak?
 
Did you just pull that out of your hat? I sync my phone multiple times a day and my backup time was still quite lengthy.

Actually I find that if I backup my iPhone several times a week, it finishes rather quickly. The more I wait and more changes I make on it (new apps, etc) the longer it takes. I got back from a ten day vacation and it took almost an hour.
