So I left my iPad upgrading over night and on first impressions I though that everything was OK, that was until I tried to open some applications.
The apps that come with iOS, Calendar, Mail , Contacts etc all opened up fine but any application that I have downloaded/purchased would not open at all. I had thought maybe I have not got the updates, so I down loaded all of the updates. While they were updating I had a tweet from @aedney.
"@geekcomputers try downloading something new from the store and then try opening them again. I've had it forget my apple password before!"
This is what sent me down the right path. When setting up iOS5 it asked me to enter my Apple ID which I did, I used is my Mobile Me account. However this is not my iTunes account, as I have had this way before I started on the Mac platform. When I tried to download a new application I saw that it had my Mobile me account. Once all the updates had downloaded and synced then ALL my applications worked once more. I then changed my Apple ID on the iPad to my iTunes store password.
If you need to change this on your iPad go to :
Settings -> Store
From there you can change your ID. Everything is now as it should be.
