Why are you sending them back?

If you are expecting warranty work, or a refund, you need to put your iPhone back to a restored condition.

What your "mack" has to do with this, I'm not sure.

if i send my phone to apple and they cannot fix it and its under apple care wil they give me an iphone 3g or a second generation like i had

They will probably send you a refurbished 2G phone.
