You can us I'Il ... (I will) when you offer something or decide to do something:
* My bag is very heavy. I'Il carry it for you.
* I'Il phone you tomorrow, Ok, Ok bye.

* I'm tired I think I'll go to bed early tonight.

* I'Il phone you tomorrow, Ok? (not I phone you).
* I think I'Il go to bed early. (not I go to bed).
Shall I ... ? Shall we...? = Do you think this is a good thing to do

* Shall I phone you this evening? Yes, please.
* I'm going to a party tonight. What shall I wear?
