Will my boyfriend get a better plea if he stays in jail?

My boyfriend is currently in charlotte county jail for violation of probation. He only violated because he could not afford to pay all of his fines and he turned himself in. He went in April 26th his arraignment in June 25th. He received a plea of two years house arrest or 364 straight. We dont know if he should accept the plea so he can get out in time for our first child to be born in October. Is there a possibility that he will receive a better plea if he stays in jail and rejects the first plea. His public defender is very hard to get in touch with. He has until the 25th to figure out what he should do. I am seeking any legal advice I can get because we cannot get in touch with his defender. If he isnt going to get another plea he will get out and just deal with house arrest, but he is afraid because he has been told it is very easy to violate while on community control. Thanks for any help you can offer.
