When I click on About, it says that I have an 8330m (with Sprint) but I recently read that it will also state the model # underneath the battery. I checked today and it just says 8330. What model do I have??
Yes you definitely have an M. I have the 8330m myself and exactly like you it shows in ABOUT as 8330m but the little sticker under the battery just says 8330. Another way to be sure though is send yourself an mms and if you see the picture in the message you can be sure you have the 8330m (on Sprint only the M's have true mms).
