Your DO schools might be more appreciative but I HIGHLY recommend you consider taking some undergrad courses as a post-bac.
I was in the same situation... sub-3.0 UG because I was friggin' sick as a dog and too stubborn to leave school (what a dumb@ss!)... 3.9 Grad. I took a bunch of post-bac courses (some to re-take the med school pre-reqs and some to take new prereq courses that I hadn't had). I ended up bumping my UG above a 3.0 with a 3.99 post-bac (about 40 credits worth).
No MD schools will bother even interviewing you with a GPA like that unless you get a 45 MCAT, write REALLY good essays and explain everything, AND get stellar (I mean like "this person is the next best thing to God" stellar) LORs. And even then, it's along shot. They want committment to medicine to be evident and seeing that you're still going on a low UG GPA without showing them that you can do better now in those same types of courses as a post-bac really shows a lack of drive as far as they're concerned.
I know it's probably not what you want to hear, but you could do what I did (only be smart about it and apply to DO schools) and try and apply now. It might be a waste of money but I do believe some DO schools would be friendly towards you with the right ECs and LORs. Then, if no bites, you can talk to the AdComs and get suggestions about how to improve your app for next time. Guranteed they will at least say do post-bac work (will ask for other things if you lack in other areas, too).
BTW-- I applied a few years ago (not to DO schools though) and was totally unsuccessful. Not even an interview. I got my butt in gear and did things I suspected I ought to have done before, reapplied this past season and got a bunch of interviews and accepted at all but one of those (and it was mixed, DO and MD acceptances... just the DO accepts came much earlier in the season).
So, yeah, it can be done with work. I do think a few of the DO schools would have accepted me when I applied before, but I didn't know much about it and refused to consider it (I work at a top med school... lots of negativity here about it when I asked around, so that was all I had to go on!). Anyway, I did my OWN research on it for this round of apps and found that I'd be perfectly happy if that was the only type of school to accept my old butt.
If you need any advice, just PM me. Been there, done that. I'm happy to pass along some of the stuff I learned-- that's what I love about SDN. We share the knowledge from our collective legwork.
