How can I restore an iPod touch if the home button is broken and I don't know the password?

I just bought my iPod Touch (4th Generation 8GB) from my friend and the home button doesn't work. Then, my parents took it away for about 6 months and I just got it back and I forgot my password. Then, I tried to get in too many times and now it says "iPod Disabled Connect to iTunes". Then, when I connect it to iTunes, it says for my to put in my password so it can connect. I've been trying to get back in but haven't found a way to restore it. HELP!!!!!

P.S. It's jailbroken, but the damage isn't due to Cydia. Also, I can't put it into DFU mode since the home button is broken.
