iPhone 3G backup session failed

Hello,

I've looked through the forums here for answers, but, I've yet to see one that matches up with the isuse I'm having.

OK, I sold my new ex-girlfriend my iPhone 3G and got a 3GS. I did the update and restore on my MacBook Pro, setup her old data, and added the music she'd purchased. All works fine, phone makes calls and all that jazz.

She has a Dell laptop and I told her to update iTunes to the latest version and then plug the phone in to her computer. The iPhone is recognized and show's up in the left-hand bar. But, when she right-clicks and tries backing up it will try to begin and then throw the error message that the backup session could not be completed.

There is no firewall software on the laptop other than the built-in WinXP b.s. The anti-virus software is the free version of AVG.

Does anyone know if there is a place that can relay more detailed error messages for the Win version of iTunes? Do you think it has to do with the phone being updated and setup on a Mac but now being used on Windows? Will I have to redo everything using her computer?

Any help or direction will be greatly appreciated.

Thanks,
Shawn

MacBook Pro Core 2 Duo, Mac OS X (10.5.7)

Go to itunes/settings/devices and see if there are any old backups left. If yes, delete them.
Did you try a manual backup by right clicking on the phone in the device list in itunes and choosing back up?

Hello, yes, the iPhone will backup on my laptop. If I can get over there I'll try the user thing on the WinXP laptop.

I'm actually beginning to think that the issue may be her hardware - it's an older Dell and I think the USB may be 1.1, not 2.0. If that's the case I'd imagine there couldn't be a data transfer. It is recognized, but, can't do anything else. I need to look into that more so this can all be done with.

If she does not have USB 2.0 that could cause the problem. I read some posts where 1.1 worked, but I wouldn't relay on a slow connection if I risk losing my backup or sync everytime I connect the phone.

You could try to copy a successful backup from your mac to her pc and see if itunes recognizes it.

Then try to sync again to the pc. But that's just an idea how it could work.

(newbie to forum here)Hi all,I had the same error with my iPod touch but never really paid attention until now that I bought the 3.1 update. It would not update due to a backup failure but now I got it to work. I went to my firewall ad I saw that "Applemobilebackup.exe" was blocked by my firewall. I just gave it accsess and the update went trough. Yay!!! good luck guys
