An iPhone has been detected, but it could not be identified properly

I'm having the exact same problem after upgrading iTunes to 8.2.0.23. Hopefully somebody will have a solution.

Are you using Vista 64 bit by any chance?

I'm on my work PC (XP Professional). Vista 64 at home. I haven't tried to sync there.

I restored my iPhone from the Settings screen last night (my Vista 64 bit Dell) when I went to sleep (says it takes two hours) and this morning it was a brick because it was wiped but iTunes couldn't connect to it to activate it. As soon as I put it in the cradle at work (Dell XPS WinXP sp2) it was recognized and activated (but without any of my settings, apps, photos, ringtones, etc.). I copied the iTunes backup file from my home computer to the same directory on my laptop at work and am now restoring from that backup. It looks like I will be completly whole again except I don't know whether or not my phone will be able to connect to iTunes at home tonight or not. I want to get this straightened out before next Wednesday, if you know what I mean.

What happens next Wednesday?

The new iPhone 3.0 operating system becomes available for download. Lots of improvements coming from that even if you don't upgrade to the new iPhone 3Gs on Friday.

Hmm, time for Apple to admit iTunes 8.2 has a flaw. My iPhone 3G connected with no problem under iTunes 8.1. I have gone through the full check list of things to do with no resolution. What happens if the only way to update to OS 3.0 is through iTunes 8.2? Can't update and can't connect?

The question that remains is Apple going to just stonewall the iPhone community util OS 3.0 becomes available tomorrow? How Microsoft of them.

I'm hoping I can upgrade my 3G at work and then iTunes will see it at home once it is running 3.0

I have Vista 64-Bit > Downloaded 8.2 software and then 3.0 update and IPhone is now a nice brick. Trying to get ITunes software on XP.

Having same issue with IPhone has been detected....

If you find a solution, please share... I'm getting the same error "an iphone has been detected, but it could not be identified properly" and my phone is now not working. Help!!!!!!!!!!

I've been experiencing this issue as well. I've tried everything suggested on the website and still no dice, anybody found a solution yet?

Guys, not sure if this will help any of you, but I was having this same issue this morning, pulling my hair out trying everything.... remembered I had just updated my AV software, so paused it and reconnected iPhone - voila! All is good.
So maybe try to pause any antivirus software you're running and see if that works?
Hope it helps

Thanks for the suggestion. I tried it but it didn't work. I still get the same message about detecting nut not identifying an iPhone.
I even upgraded to 3.0 on my work computer thinking that just maybe the iTunes glitch had to do with incompatibility wit the 2.21 firmware but I got the same exact message when I tried it again from home. It must be a Vista 64 bit issue.

I don't think it's just a Vista issue, as I'm running 64 bit XP
