When trying to access iCloud through Safari, a prompt screen asks if I want to set up iCloud on my iPad, or install Find my iPhone.
The iPad is set up and Find my phone is installed. My iCloud settings look normal and it is working-- that is, contacts, notes and address book are syncing. iOS is 5.1.1. I'm particularly dependent upon the info in my iPad and iPhone right now and am afraid to try a reinstall.
You cannot access iCloud.com using an iOS device, only a computer.
To access your contacts, notes and address book from your iPad use the pre-installed apps.
