Answer 2

"The cell phone" seems to refer to a particular phone. If you want to refer to cell phones in general, then use the plural form.

1 - OK
2 - ... on it.
3 - OK (or ... comes in.)
4 - (sentence 3 is better!)
5 - (I'd omit "on the phone" because it's repetitive.)
6 - The cell phone vibrates when an alarm goes off.
