iCloud arrangement with iPad2, iPhone 4 and iPhone3G

Hi there

My question is straightforward, but with a rather complicated background.

The question is basically, can you add a second iCloud email account to an iPad and can you set up an iCloud email account (without any of the other iOS5 features etc) on an iPhone 3G

I have an iPhone 4, my girlfriend has an iPhone 3G and we share an iPad 2 (synced with my iTunes account) and Macbook Pro. The iPad has both our email accounts on it.

I am going to be moving my MobileMe over to iCloud, but since my girlfriend only has my old iPhone 3G (and currently uses Gmail), she won't be able to use iCloud on her phone. She will be upgrading her phone sooner or later, so it would be useful for her to get an iCloud account also.

To try to get this working, I'm thinking of restoring the iPad as a new device with my girlfriend's iTunes so that she can use the iPad to get iCloud. But, I would want to be able to access my iCloud email account on the iPad also. Another thing to think about is whether my girlfriend will be able to access iCloud email on her iPhone 3G?

Any ideas?

Thanks in anticipation!
