Why did my iphone overwrite my back up?

I backed up my phone about a week ago. I forgot to back it up before I decided to downgrade to 4.0.1. After I downgraded it said I could not restore to my last back up because it was not the same version. (the back up was 4.2.1) So then I set it up as a new iphone and synced everything back on it. There was no contacts or pictures or any of that. Eventually I said forget it and I "upgraded" the phone. I then restored it to the last back up. When it got done, I still had no contacts or anything. I tried to restore it from the last 3 back ups and they are all basically empty. Is there anything I can do? The last back up that works is from October.
