I think my opinion would have to be based on when you were planning to take the DAT, and how well you did on it.
As of now, it sounds like you yourself think it would be a bad idea to apply (or that you don't feel ready), given that you believe it'll all be a waste of time. Given your sGPA, I'd probably focus on doing some post-bacc sciences, and doing extremely well on them (you know, the ones all the schools typically recommend in addition to their pre-reqs: biochem, histo, immuno, A&P, etc).
As for which schools might accept you with your GPA/sGPA, take a gander at doc toothache's spreadsheet here:
It shows for almost every school the range of their accepted student's GPA and science GPA, and from the looks of it, there are quite a number of schools that took applicants with GPAs in your range (looking at the low end). One thing to keep in mind is that some of these schools are state schools that are mostly in-state friendly, so even if they took someone with a 2.30, that person might've had an in-state advantage.
