Many school like lower the GPA for RN-BSN students. Where I live, it's 2.5. You are already a nurse..there's nothing to prove at the bedside. They know you have what it takes and if you are wanting to get a BSN, you are more likely to finish it than a pre-nursing student. You are basically extending it, so they can be more flexible. Many of the classes are online and there's a lot of money for the university to make. If they turned away anyone with less than a 3.0, they would lose a lot of prospects. Returning students have families or they went to school years ago, so they like getting students into the program because if you finish it, that means more money for the school.
Where I live, there isn't even a selection process. There's no wait list and you don't have to beat out other student with better GPA's. If you meet the minimum requirements, you are automatically accepted. The only limitation is if the class is full. Many of the classes are for RN-BSN students only. Your classmates are all RN's too, so instructors don't have to spend lots of time teaching the basics. I think you are in a pretty good spot. See what university will enroll you with your requirements. You may find it easier than you think. It's nothing like getting into nursing school for the first time.
