I commented on your question yesterday, so see that response as well. It sounds like you took the plea deal you,we're offered, which if that was the case there isn't much you can do. Don't plead guilty to charges you dont think you are guilty of. Demand a trial instead. It's your right.
You can make a motion to withdraw your guilty plea, however that is a tough standard to meet. You may be stuck.
