my son will be 3 in a few weeks, and he is having a hard time with potty training as well. He KNOWS what to do, has for a long time .. he just doesn't seem to care if he wets or soils himself! aarrg. we have him in undies in the day, and he could care LESS if he wets himself. we remind him to go on the potty all the time, and half the time he says "I don't have to go" and gets mad if I have him sit on the potty to at least try.
I have to admit he does love the excitement of when he DOES go pee and poop in the potty, cause we really play it all up. He has a folder in the bathroom with paper and stickers in it. when he goes pee, he puts a star sticker on his paper in the folder, and when he goes poop, he puts a circle sticker .. then he gets pee and poop candy (colored m&m's for pee, brown for poop LOL) and LOVES his potty candy. but he just doesn't seem interested in stopping whatever he's doing to go. sigh.
so I wish I could help ... but I think I am going to keep reading this thread and see how many ideas I can glean from this. good luck!
