Clockworkmod Recovery on 2.1 Eclair?

[Alex.Kim]

So I flashed back to stock 2.1 Eclair using Odin, and now I want to install Clockworkmod. I would update to 2.2 and use Rom Manager, but Kies keeps telling me my phone is unregistered and I can't update it. Anyways, I was wondering if I could download CWM from here and flash it as an update.zip. If that doesn't work, I just need any way to install CWM onto 2.1 Eclair. Thanks
