upgrading Ubuntu

[MICHAEL WEAVER <michaelweaver1 btinternet com>]

I am thinking of upgrading Ubuntu from Dappa Drake to Edgy.
If I were to do it on my laptop which is the only PC I have with Linux 
on would I get speech during the upgrade and can it also be done without 
having to upgrade over the Internet as although I have a wireless 
network card for my Local Linux User Groups I don't have a wireless 
router at home for setting up my BT connection.
I would do it on my desktop only I need to backup my address book, I 
don't know if the Edgy CD Talks and I haven't been able to test Ubuntu 
with my BT Voyager.
