Upgrade to 3.1 software then back up issues

I hope someone can help....

When I plug in my phone to my PC I click on 'yes' to upgrade the software to 3.1. I've downloaded the latest version of iTunes and the upgrade seems to install OK but then I get 'backing up "phone name"' and this takes forever. I left it for 12 hours one night and it still had only reached half way on the progress bar.

I only have 3 applications installed on my phone.....can someone please help or give me a number to contact Apple - the number seems to be hidden on their site!

Thanks in anticipation

 

yes, i meant 3.1.2

thanks, i'll give it another go.

 

Just tried again, i've clicked on 'install' to get the 3.1.2 update, it then gives me a box saying 'backing up xxxxxxx' but there is no option to 'x' (close) the box and I have to unplug my phone which then brings up a message to say 'back up not successful because my phone was disconnected'.

Any other advice??

 

No, there is nothing happening in this box, it's a pop up box with no option to close and just says 'backing up xxxxxx' with the green progress bar.
