"I give you a cake and you deliver it to my friends" means "I (habitually) give you a cake, and you (habitually) deliver it to my friends." It does not necessarily mean that I want you to deliver the cake to my friends; only that that's is what you do with it.
"I give you a cake to deliver to my friends" means "I (habitually) give you a cake that I want you to deliver it to my friends." It does not necessarily mean that you actually deliver the cake to my friends
Thank you Florentina and i have a question to know if i learned it or not;
Would you say that the following sentence is true or not?
"I will call you to give an information about latest news." Does it mean that you actually give an information to me about what i want (le.g. latest news)?
"Information" is not countable; don't use "an" with it.
It means that your present intention is to call, and to give information about the latest news. We don't know if you'll actually do it; the call hasn't happened yet. (Edit: Your sentence says that the speaker is giving the information. I'm not sure based on your post if you understood that.)
