Bear with me if I'm being stupid but I only got my iPad 5 days ago... I have spent all evening trying to upgrade to OS 4.3 and failing. I go into iTunes and it gives me a little message saying I haven't transferred my purchases, so I sync the iPad. Then I start downloading the update which takes about 20 minutes. Then I get a message saying the operation timed out, so I start again.... After 5 attempts I gave up. Any ideas what I am doing wrong? Ps I can't work out how to do a backup either, please could someone explain?
