Considering switching from an Android to the iPhone - HELP [View all]

Hi there,
My husband got new hearing aids and they can be adjusted best with an Apple phone so we might have to switch (phones already paid).

That said, can anyone answer the following for me:

1. We have all our contacts in Google - do they transfer to the iPhone?
2. We have lists in Google - do they transfer to the iPhone?
3. We have e-mail from gmail and Yahoo (ATT) mail - can I get them on the iPhone?
4. How well does stuff sync from the iPhone to a regular Windows PC?
5. Finally - how does the iPhone work AS A TELEPHONE!?!!?

We'd be using Verizon as our carrier (corporate discounts)

We don't live & die by our phones (often keep them off for days) but when we need them, we need them.

Thoughts?

Thanks so much
